We will be upgrading the Hsphere system packages on all Linux servers on Tomorrow, March 13, 2007 at 2:30 AM EDT (Tue 13th Mar, 5:30pm Sydney time.)
Control panel will be stopped for 2 hours or less during the process. Web services can see a downtime of 5 minutes/per server and mail-services can see a downtime of upto 10 mins/per server.
While being mostly a set of security and bug fixes, it also upgrades PHP to 4.4.6 and Postgresql to 7.4.16. We couldn’t give a 24 hour notice this time as there is a major security issue that needs to be immediately patched.
