This is to inform you that:
1)SingTel EXPAN data center will be having their power system maintenance scheduled on 10 Nov 2007 at 2200 hr till 11 Nov 2007 at 1200 hr.
The following are given by SingTel EXPAN:
============================================================================
Reason: To facilitate Annual Genset On-Load Testing at Comcentre III.
This is part of SingTel commitments to ensure resilience of the power
systems.
Impact: No impact is expected. However SingTel recommend you to back up
your critical data and/or divert your service if necessary.
============================================================================
Please do backup your data.
（In fact, all clients should do regular backups).
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).
There will be around 4 hours of downtime while we replace HDD and reinstall new OS.
Since all servers will have to be upgraded to PHP5 by end of this year:
http://sghosting.blogspot.com/2007/07/go-php-5.html
we do it together with HDD change for Gold server.
MySQL will be upgraded to version 5 as well accordingly.
(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.)
Thank you for your attention and cooperation.
