<div style="background-color: white; color: #222222; font-family: Arial; font-size: 14px;">
<br />
A couple moment ago (8:30PM, 20 Apr 2015), we detected a network outrage which brought interruption for our network. Upon checking, the server on IP <wbr></wbr>113.11.251.22 was receiving over 2Gbps DDOS attack. Since the DDOS attack traffic is so high that firewall could not stop it, we are currently null route ( black hole ) IP 113.11.251.22 for the moment, all domains hosted on this server is not functioning as a result.<br />
<br />
And unfortunately we are not able to know how long the attack will last. We are closely monitoring the situation and will bring it up once we see the attack is over.</div>

We apologise for the inconvenience caused to customers on IP 113.11.251.22, but DDOS attack is not predictable or preventable, we have to bring down the server in such case. Even if we leave the server up, all web sites and emails would not be accessible because of the attack.</div>

<br style="background-color: white; color: #222222; font-family: arial, sans-serif; font-size: 13px;" />
<span style="background-color: white; color: #222222; font-family: arial, sans-serif; font-size: 13px;">As part of our continuous commitment to provide better service and better hosting experience to our valued clients, we would like to hereby announce that a major data centre migration and consolidation exercise will be carried out in December 2014.</span><br />
<span style="background-color: white; color: #222222; font-family: arial, sans-serif; font-size: 13px;"><br /></span>
<span style="background-color: white; color: #222222; font-family: arial, sans-serif; font-size: 13px;">Where are we migrating to?</span><br />
<br style="background-color: white; color: #222222; font-family: arial, sans-serif; font-size: 13px;" />
<span style="background-color: white; color: #222222; font-family: arial, sans-serif; font-size: 13px;">We will be migrating all our servers from the present data centres at Global Switch @ Tai Seng to Pacnet Singapore SGSC2 @ Paya Lebar.</span><br />
<span style="background-color: white; color: #222222; font-family: arial, sans-serif; font-size: 13px;"><br /></span>
<span style="background-color: white; color: #222222; font-family: arial, sans-serif; font-size: 13px;">As a leading provider of integrated technology solutions for enterprise and carrier customers, Pacnet owns and manages the longest privately-owned subsea cable network, measuring up to 46,000 km, in the Asia-Pacific region with more than 110 Points of Presence (PoPs) around the world.</span><br />
<span style="background-color: white; color: #222222; font-family: arial, sans-serif; font-size: 13px;"><br /></span>
<span style="background-color: white; color: #222222; font-family: arial, sans-serif; font-size: 13px;">Why are we migrating?</span><br />
<br />
<ul>
<li><span style="background-color: white; color: #222222; font-family: arial, sans-serif; font-size: 13px;">Redundant network connectivity.</span></li>
<li><span style="background-color: white; color: #222222; font-family: arial, sans-serif; font-size: 13px;">Reduced network downtime by having redundant network connectivity from multiple bandwidth providers.</span></li>
<li><span style="background-color: white; color: #222222; font-family: arial, sans-serif; font-size: 13px;">Pacnet SGSC2 is fully compliant with the Monetary Authority of Singapore (MAS) security guidelines and is further confirmed by the independent third party Threat Vulnerability Risk Assessment (TVRA).</span></li>
<li><span style="background-color: white; color: #222222; font-family: arial, sans-serif; font-size: 13px;">Pacnet SGSC2 is also PCI DSS 2.0, ISO 9001 and ISO 2700 certified.</span></li>
<li><span style="background-color: white; color: #222222; font-family: arial, sans-serif; font-size: 13px;">Better network accessibility in terms of speed and stability.</span></li>
</ul>
<br />
<span style="background-color: white; color: #222222; font-family: arial, sans-serif; font-size: 13px;"><br /></span>
<span style="background-color: white; color: #222222; font-family: arial, sans-serif; font-size: 13px;">Who will be affected?</span><br />
<br style="background-color: white; color: #222222; font-family: arial, sans-serif; font-size: 13px;" />
<span style="background-color: white; color: #222222; font-family: arial, sans-serif; font-size: 13px;">All clients currently hosted under SingaporeWebHosting.com will be affected by this migration exercise. </span><br />
<span style="background-color: white; color: #222222; font-family: arial, sans-serif; font-size: 13px;"><br /></span>
<span style="background-color: white; color: #222222; font-family: arial, sans-serif; font-size: 13px;">When will this happen?</span><br />
<br style="background-color: white; color: #222222; font-family: arial, sans-serif; font-size: 13px;" />
<span style="background-color: white; color: #222222; font-family: arial, sans-serif; font-size: 13px;">The migration and consolidation exercise will be carried out in several small batches in order to ensure a smooth migration:</span><br />
<br />
<div class="p1">
<span class="s1">Date: 18th, 19th, 25th, 26th, December 2014</span></div>
<div class="p1">
<span class="s1">Time: 11.00 PM</span></div>
<div class="p1">
<span class="s1">Estimated Server Uptime: 7.00 AM</span></div>
<br style="background-color: white; color: #222222; font-family: arial, sans-serif; font-size: 13px;" />
<span style="background-color: white; color: #222222; font-family: arial, sans-serif; font-size: 13px;">What will happen during the migration?</span><br />
<br style="background-color: white; color: #222222; font-family: arial, sans-serif; font-size: 13px;" />
<span style="background-color: white; color: #222222; font-family: arial, sans-serif; font-size: 13px;">1.We will physically unplug the servers from the present Global Switch Data Centre and transport them to the new Pacnet Data Centre located at Paya Lebar.</span><br />
<span style="background-color: white; color: #222222; font-family: arial, sans-serif; font-size: 13px;">2.An Estimated 6-8 hours of downtime is to be expected during the migration exercise.</span><br />
<span style="background-color: white; color: #222222; font-family: arial, sans-serif; font-size: 13px;">3.There will be NO changes of IP addresses to your hosting accounts / servers upon the completion of the new data centre migration.</span><br />
<span style="background-color: white; color: #222222; font-family: arial, sans-serif; font-size: 13px;"><br /></span>
<span style="background-color: white; color: #222222; font-family: arial, sans-serif; font-size: 13px;">What Are The Things You Need To Prepare?</span><br />
<br style="background-color: white; color: #222222; font-family: arial, sans-serif; font-size: 13px;" />
<span style="background-color: white; color: #222222; font-family: arial, sans-serif; font-size: 13px;">We recommend all users to run a full data backup that are currently hosted in your subscription with us to your local desktop/laptop/external drive as an extra precaution for this migration exercise.</span><br />
<br style="background-color: white; color: #222222; font-family: arial, sans-serif; font-size: 13px;" />
<span style="background-color: white; color: #222222; font-family: arial, sans-serif; font-size: 13px;">Once again, we would like to thank you for your support, your kind understanding and your great patience. Upon completion of this migration and consolidation exercise, we believe that we will be able to provide you with better service that will guarantee a better hosting experience with us.</span><br />

Dear Customers,<br />
<br />
Recently we noticed a few cases of spam emails sent from domains hosted with us. All our customers are legitimate businesses and do not send spams themselves, however virus affected computers, weak or leaked passwords, hacked web application, etc. may cause spam emails sent from your account.<br />
<br />
Please note, spamming is strictly not allowed on our servers, and it's customer's responsibility to secure their own computers, passwords and applications and make sure they are not compromised.<br />
<br />
If any account is found sending spam emails, for whatever reason, the account will be suspended immediately without notice and it will not be re-activated.<br />
<br />
Please understand, spamming is very serious issue in hosting industry, it may cause server IP blacklisted therefore cause lots of problems to many other customers on the same server. We must take strong action promptly to protect all our customers.<br />
<br />
To avoid email account compromised and account suspended, please do these immediately, yes, I mean NOW:<br />
<br />
1)Warn all your users not to open any unexpected email attachment, which contains virus in most cases. Do not download anything from web sites that you do not really know.<br />
<br />
2)Keep your anti-virus/firewall software updated and scan all your computers everyday.<br />
<br />
3)Warn your users not to leak password, personal info etc. to anyone, especially online. Do not post your email address online if possible.<br />
<br />
4)Change all your email account passwords to strong ones: min 8 characters with random combination of capital/small letters, numbers and special characters, no dictionary words, no username or part of username in password, no personal information in password, no company name / telephone number / calendar dates etc. It's advisable to use the password generator in cPanel.<br />
<br />
5)Change all your email passwords regularly.<br />
<br />
6)Do not login to your email on any public computers such as in hotel, airport, library, Internet cafe etc.<br />
<br />
7)Keep your web application and scripts updated and patched up.<br />
<br />
8)Do NOT use the same password for different accounts or services, for example, do NOT use the same password for your email as your Facebook/Twitter etc. account.<br />
<br />
9)If possible, do NOT user common names as email address such as admin@yourdomain, support@yourdomain, info@yourdomain, test@yourdomain etc.<br />
<br />

There is a need to increase bandwidth due to the number of fibre users increasing in Singapore. If we continue to stay in SingTel (Expan) DC, we would have problems to provide normal service to our clients as the price of rack space rental and bandwidth of SingTel EXPAN DC is very high compared to other data centers and have been increasing around 15% every year, and we would have limited choice of network links since SingTEL EXPAN DC is not a carrier neutral data center.</span><br style="background-color: white; color: #222222; font-family: arial, sans-serif; font-size: 13px;" /><br style="background-color: white; color: #222222; font-family: arial, sans-serif; font-size: 13px;" /><span style="background-color: white; color: #222222; font-family: arial, sans-serif; font-size: 13px;">Sorry for the scheduled downtime and inconvenience caused, and thank you for your kind understanding and continued support.</span><br style="background-color: white; color: #222222; font-family: arial, sans-serif; font-size: 13px;" /><br style="background-color: white; color: #222222; font-family: arial, sans-serif; font-size: 13px;" /><span style="background-color: white; color: #222222; font-family: arial, sans-serif; font-size: 13px;">Kindest regards,</span><br style="background-color: white; color: #222222; font-family: arial, sans-serif; font-size: 13px;" /><span style="background-color: white; color: #222222; font-family: arial, sans-serif; font-size: 13px;">SingaporeWebHosting.com Support</span>Singapore Web Hostinghttp://www.blogger.com/profile/02998197530730395102noreply@blogger.comtag:blogger.com,1999:blog-12961804.post-33516536676598031302012-02-07T13:29:00.003+08:002012-02-07T18:18:10.252+08:00Server Migration Due to CentOS 4 EOLDear Customers,<div><br /></div><div><span style="font-family: Arial; text-align: -webkit-auto; background-color: rgb(255, 255, 255); font-size: medium; ">CentOS 4 will be EOLed (End-Of-Life) after Feb 29, 2012:</span></div><div><span style="font-family: Arial; text-align: -webkit-auto; background-color: rgb(255, 255, 255); font-size: medium; "><br /></span></div><div><a href="http://www.centos.org/modules/smartfaq/faq.php?faqid=42">http://www.centos.org/modules/smartfaq/faq.php?faqid=42</a> </div><div><br /></div><div>Some of our servers are running on CentOS 4 and we have to upgrade them all to latest CentOS 6. Doing backup, then re-installing OS then restoring all accounts on existing server will take 12 hours and cause long downtime. To avoid service disruptions, we decided to move accounts currently on CentOS 4 server to new server running CentOS 6. The process will not cause any downtime. </div><div><br /></div><div>We will start migration today 7 Feb 2012, and will update here when it's all done.</div><div><br /></div><div>However, please note:</div><div><br /></div><div>1)Users may notice warning message in cPanel:</div><div><br /></div><div><span style="font-family: verdana, arial, helvetica, sans-serif; font-size: 11px; text-align: -webkit-auto; background-color: rgb(255, 255, 0); ">This copy of cPanel / WHM is a trial version and will expire at the end of the trial term.

But for domains that are not using our nameservers and not registered via us, you have to update domain DNS records to new IP address yourself as the domain is not in our control. We will inform users who need to update DNS records by email, please update ASAP after receiving our email. The old servers will be shutdown after migration and the domains will stop functioning if DNS record is not updated by that time.</div><div><br /></div><div>Thank you for attention.</div><div><br /></div><div>SingaporeWebHosting.com</div>Singapore Web Hostinghttp://www.blogger.com/profile/02998197530730395102noreply@blogger.comtag:blogger.com,1999:blog-12961804.post-79850881847647037022011-12-23T07:08:00.002+08:002011-12-23T07:17:02.122+08:00Scheduled Maintenance & Downtime During The WeekendThere was HDD errors with Gold server on 22 Dec that caused downtime from around 12:30PM to 7PM.<br /><br />We've managed to bring the server up but there will be urgent HDD replacement in this coming weekend after 11pm till 6am (meaning Sat or Sun, yes we will do it on Christmas Eve or on Christmas day to reduce impact).

If you still cannot access your domain, it's either because your ISP hasn't updated their DNS cache or your domain is not using our nameservers, you need to update A record for your domain yourself.<br /><br />Thank you for your patience and understanding.<br /><br /><br />Update 7PM 15 Sep: The attack is still ongoing, and the worst thing is, we do not know when it will be over.<br /><br />So we have managed to get new IP addresses for our server and changed our server IPs. If your domain is using our nameservers (you should), you do not need to do anything. We've made changes to our DNS IPs and sites should be up soon.<br /><br />If your domain is NOT using our nameservers, please change server IPs yourself. Just change IP from 203.175.160.x to 203.175.163.x<br /><br />For example, if you are currently using 203.175.160.74, change it to 203.175.163.74<br /><br />If yours is reseller account, you need to change your nameserver IPs instead of account IP.<br /><br />-------------End Update-----------<br /><br />Bad News !<br /><br />There's Heavy DDOS attack to our uplink provider's network, 1gbps attack, the worst one in past few years to whole Singtel network. All our servers (and many other hosting providers on same network) are not accessible from around 1:30pm 15 Sep.<br /><br />The attack is against other server, not ours, but it's too heavy, all servers on the network are affected.<br /><br />We are monitoring and trying our best to find a solution but cannot estimate when the attack will be over since it's out of our control, not even in Singtel's control.<br /><br />Will post here when there's updates.<br /><br />Sorry for inconvenience and thank you for kind understanding.<br /><br />SWH<br /><br />PS. backup server is not a solution for such DDOS attack. As the whole network is under attack, all servers are not accessible. It's not practical to maintain a backup server for all servers in another datacenter. Even if it's possible to maintain backup servers in another datacenter, moving all account data to the other datacenter, making changes to IP address, waiting for DNS update, it would be a few days later considering the amount of domains/accounts affected.Singapore Web Hostinghttp://www.blogger.com/profile/02998197530730395102noreply@blogger.comtag:blogger.com,1999:blog-12961804.post-629272521559230462008-08-07T20:43:00.004+08:002008-08-07T20:53:15.763+08:00Scheduled Maintenance at Sintel EXPAN DatacenterPlease be informed that Singtel EXPAN datacenter will be conducting <span style="font-weight: bold;">scheduled maintenance on 16 Aug AND 17 Aug, 2008.</span><br /><br />All customers, especially VPS, dedicated server and server colocation customers, please do your own backup before implementation of the maintenance.<br /><br />The following is given by SingTel.<br /><br />************************************<br />Dear Customers,<br /><br />SingTel EXPAN will be conducting* Cyclical UPS Parts (Capacitors and<br />Fans) Replacement* in accordance to guidelines set by UPS manufacturer;<br /><br />_*Commencement Date/ Time*_**<br /><br /><span style="font-weight: bold;">*16-08-08/ 1700hrs (SGT) to 17-08-08/ 0730hrs (SGT)*</span><br /><br /><br />_*Purpose of Works*_**<br /><br />Following the recommended cyclical parts replacement guidelines set by<br />the UPS manufacturer, the AC/DC capacitors and fans for the UPS 5-1 and<br />6-1 have to be replaced.

Hope it's finally fixed, instead of kind of testing.<br /><br />There're only a few clients on our Windows server, but if you happen to be on Windows server and wondering why your web site and email is not accessible from this morning til this moment 5PM 1 June 2008, and counting, here's the news on fire at ThePlanet datacenter, where our Windows server is located:<br /><br /><blockquote> From Doug Erwin:<br />This evening at 4:55pm CDT in our H1 data center, electrical gear shorted, creating an explosion and fire that knocked down three walls surrounding our electrical equipment room. Thankfully, no one was injured. In addition, no customer servers were damaged or lost.<br /><br />We have just been allowed into the building to physically inspect the damage. Early indications are that the short was in a high-volume wire conduit. We were not allowed to activate our backup generator plan based on instructions from the fire department.<br /><br />This is a significant outage, impacting approximately 9,000 servers and 7,500 customers. All members of our support team are in, and all vendors who supply us with data center equipment are on site. Our initial assessment, although early, points to being able to have some service restored by mid-afternoon on Sunday. Rest assured we are working around the clock.<br /><br />We are in the process of communicating with all affected customers. we are planning to post updates every hour via our forum and in our customer portal. Our interactive voice response system is updating customers as well.<br /><br />There is no impact in any of our other five data centers.<br /><br />I am sorry that this accident has occurred and I apologize for the impact.</blockquote>Sadly it's not in our control and at this time we do not have an estimate...<br /><br />Update at 1PM 2 June: It's still not up after more than 1 day. Here's update from the datacenter:<br /><br /><blockquote>As previously committed, I would like to provide an update on where we stand following yesterday's explosion in our H1 data center. First, I would like to extend my sincere thanks for your patience during the past 28 hours. We are acutely aware that uptime is critical to your business, and you have my personal commitment that The Planet team will continue to work around the clock to restore your service.<br /><br />As you have read, we have begun receiving some of the equipment required to start repairs. While no customer servers have been damaged or lost, we have new information that damage to our H1 data center is worse than initially expected. Three walls of the electrical equipment room on the first floor blew several feet from their original position, and the underground cabling that powers the first floor of H1 was destroyed.<br /><br />There is some good news, however. We have found a way to get power to Phase 2 (upstairs, second floor) of the data center and to restore network connectivity. We will be powering up the air conditioning system and other necessary equipment within the next few hours. Once these systems are tested, we will begin bringing the 6,000 servers online. It will take four to five hours to get them all running.<br /><br />We have brought in additional support from Dallas to have more hands and eyes on site to help with any servers that may experience problems. The call center has also brought in double staff to handle the increase in tickets we're expecting. Hopefully by sunrise tomorrow Phase 2 will be well on its way to full production.<br /><br />Let me next address Phase 1 (first floor) of the data center and the affected 3,000 servers. The news is not as good, and we were not as lucky. The damage there was far more extensive, and we have a bigger challenge that will require a two-step process. For the first step, we have designed a temporary method that we believe will bring power back to those servers sometime tomorrow evening, but the solution will be temporary. We will use a generator to supply power through next weekend when the necessary gear will be delivered to permanently restore normal utility power and our battery backup system. During the upcoming week, we will be working with those customers to resolve issues.<br /><br />We know this may not be a satisfactory solution for you and your business but at this time, it is the best we can do.<br /><br />We understand that you will be due service credits based on our Service Level Agreement. We will proactively begin providing those following the restoration of service, which is our number priority, so please bear with us until this has been completed.<br /><br />I recognize that this is not all good news.

However SingTel recommend you to back up<br />your critical data and/or divert your service if necessary.<br />============================================================================<br /><br />Please do backup your data.<br /><br />(In fact, all clients should do regular backups).<br /><br />2)We are going to replace hard drives on Gold Server and upgrade PHP/MySQL tonight (18 Oct 2007) after midnight (19 Oct 2007 early morning).<br /><br />There will be around 4 hours of downtime while we replace HDD and reinstall new OS.<br /><br />Since all servers will have to be upgraded to PHP5 by end of this year:<br /><br /><a href="http://sghosting.blogspot.com/2007/07/go-php-5.html">http://sghosting.blogspot.com/2007/07/go-php-5.html</a><br /><br />we do it together with HDD change for Gold server.<br /><br />MySQL will be upgraded to version 5 as well accordingly.<br /><br />(If your using MySQL with different character set from default, the database may not work after upgrading from MySQL4.0.27 to MySQL5 as MySQL changed the way to handle character set. Please consult with your programmer on how to fix the character set issue.)<br /><br />Thank you for your attention and cooperation.Singapore Web Hostinghttp://www.blogger.com/profile/02998197530730395102noreply@blogger.comtag:blogger.com,1999:blog-12961804.post-66235705278194604742007-08-30T02:58:00.000+08:002007-09-01T07:06:34.489+08:00Scheduled Maintenance on Gold ServerUpdate 1 Sep 2007, 7AM: We have to arrange another time for the maintenance. Started accounts backup from 10:20PM last night till now, unfortunately it's still not completed yet. It would cause too long downtime (estimated 10 hours+) this way. We will find a better solution and arrange another time. Will keep you informed.<br /><br />Please be informed that we are going to replace hard drives on Gold Server and implement hardware maintenance on this coming Friday night, 31st Aug 2007.<br /><br />As you know, no hardware can last forever, so normally we replace HDD every 18-24 months on all servers as routine maintenance.<br /><br />Now it's time for Gold Server.<br /><br />Another reason that we decided to carry out hardware maintenance on Gold server now is that <a href="http://sghosting.blogspot.com/2007/08/problem-with-gold-server.html">Gold server has been having hardware problems this month</a>. Our investigation shows that possible causes include:<br /><br />1)HDD bad sectors<br />2)Kernel bug<br />3)BIOS needs to be updated<br />4)Combination of above<br /><br />To be honest, hardware failure is unavoidable as you can understand, but the worst thing this time is the bad timing.<br /><br />Our original plan was to move as much accounts as possible to new server before we change HDD to avoid or reduce service disruption. However, the new server ordered has not been delivered till now and we don't expect it to arrive in next 1 or 2 days.<br /><br />We simply cannot wait anymore considering current situation. So we decided to go ahead ASAP.<br /><br />But, updating BIOS is a bit risky. If anything went wrong, the whole server would be spoiled and become useless. In it did happen, we must change the whole server. Therefore we bought a server from other hosting company, at rather high cost.<br /><br />Please rest assured, we will try our best to complete the maintenance and keep servers in good shape.<br /><br />The hardware maintenance for Gold Server is scheduled on 31st, Aug 2007, from around 11PM to 5AM next morning, 1st, Sep 2007 .<br /><br />Expected downtime is 6 hours while we replace HDD, install OS, update BIOS/kernel. Hopefully it will be shorter if everything goes smoothly, but it might be longer.<br /><br />You can check which server your account is on via IP address:<br /><br /><a href="http://sghosting.blogspot.com/2005/05/how-do-i-know-which-server-my-site-is.html">http://sghosting.blogspot.com/2005/05/how-do-i-know-which-server-my-site-is.html</a><br /><br />Sorry for inconvenience caused and thank you for your kind understanding.Singapore Web Hostinghttp://www.blogger.com/profile/02998197530730395102noreply@blogger.comtag:blogger.com,1999:blog-12961804.post-79507687885180076032007-08-02T17:00:00.000+08:002007-08-29T12:25:09.174+08:00Problem with Gold ServerUpdate 12:20PM 29 Aug: It's up now.

And most importantly, we will do hardware maintenance asap. More details will be posted when schedule is confirmed. Sorry for the downtime and trouble caused to users.<br /><br />Update 11:50AM, 29 Aug: Gold server is having same issue again now. We know it's bad. We'll bring it up and update here.<br /><br />Update 3pm, 21 Aug: Gold server is up now. We're investigating. Will update here if further action/maintenance is needed.<br /><br />Update on 21 Aug: Gold server is having problem again today from around 11am. We're trying our best to bring it back asap. Sorry for the trouble. Will update here once we have further news.<br /><br />Dear Customer,<br /><br />There was problem on Gold server this morning and we managed to bring it up at around 1:55pm. Sadly while we were investigating further on the server, it went down again. Our server admin is on the way to datacenter to troubleshoot.<br /><br />Very sorry for the inconvenience caused. We will try our best to bring it back as soon as possible.<br /><br />Thank you for your kind understanding.<br /><br />Update: It's up at around 5:50pm<br /><br />There might be problem with hard disk or kernel, we will investigate to see if it's hard disk, if so, we will have to change HDD as soon as possible, most likely tonight or tomorrow night.<br /><br />Therefore, unfortunately, there might be urgent HDD maintenance and downtime tonight or tomorrow night. We'll make announcement to all clients and post updates here.<br /><br />Clients on Gold server, please do NOT do backup or upload anything until maintenance is complete.<br /><br />Again, sorry for inconvenience and thank you for understanding.Singapore Web Hostinghttp://www.blogger.com/profile/02998197530730395102noreply@blogger.comtag:blogger.com,1999:blog-12961804.post-19435417606164344582007-07-24T23:47:00.000+08:002007-07-24T23:52:10.264+08:00Go PHP 5Dear Customers:<br /><br />We will soon be dropping support for PHP version 4 since PHP developers will discontinue PHP 4 by end of this year.<br /><br />More details can be read at:<br /><br /><a href="http://gophp5.org/">http://gophp5.org/</a><br /><br />Please do read details at above site.<br /><br />PHP officially announced "PHP 4 end of life" on 13 July 2007:<br /><br /><a href="http://www.php.net/">http://www.php.net/</a><br /><br />-----------------------------<br />[13-Jul-2007]<br /><br />Today it is exactly three years ago since PHP 5 has been released. In those three years it has seen many improvements over PHP 4. PHP 5 is fast, stable & production-ready and as PHP 6 is on the way, PHP 4 will be discontinued.<br /><br />The PHP development team hereby announces that support for PHP 4 will continue until the end of this year only. After 2007-12-31 there will be no more releases of PHP 4.4. We will continue to make critical security fixes available on a case-by-case basis until 2008-08-08. Please use the rest of this year to make your application suitable to run on PHP 5.<br />------------------------------<br /><br />So, kindly make sure all your PHP applications/scripts are version 5 compatible ASAP. We only have less than 160 days to plan for the upgrading. To play safe, we will most likely upgrade before the deadline.<br /><br />For documentation on migration for PHP 4 to PHP 5, please refer to PHP migration guide:<br /><br /><a href="http://www.php.net/manual/en/migration5.php">http://www.php.net/manual/en/migration5.php</a><br /><br />In the past few years, like most of the web hosting providers, we did not upgrade to PHP 5 due to compatibility issues between PHP 4 and 5, but now all of us are forced to upgrade.<br /><br />No choice, let's move forward together.<br /><br />Please check your PHP scripts and make sure it's PHP5 compatible.<br /><br />P.S. We are not able to check your PHP scripts as we know nothing about it. Please check with your web designer/programmer.Singapore Web Hostinghttp://www.blogger.com/profile/02998197530730395102noreply@blogger.comtag:blogger.com,1999:blog-12961804.post-81149775617647929722007-06-15T13:02:00.000+08:002007-06-15T14:21:51.794+08:00EXPAN: Urgent Maintenance for UPS & Incident Report for COM3 Level2 UPS InterruptionDear Customers,<br /><br />Just received "Urgent Maintenance for UPS & Incident Report for COM3 Level2 UPS Interruption" from Singtel EXPAN.
