We will be upgrading PHP from version 5.3.x (DEPRECATED) to 5.4.x (LATEST STABLE) by Thursday 14th of August 2014. The upgrade will take place at 8:00pm UTC (Coordinated Universal Time) and it will last for one hour at the most.
While there is no timeout expected to occur during the upgrade procedure, make sure that you don't keep any sessions or files open during the upgrade.
