It was brought to my attention that I erred in my announcement of the changed date of the kernel upgrade. I posted it would be Friday August 24th, but the correct date is Friday August 26th. A customer felt this was ambiguous since the 24th was on a Wednesday not Friday and asked me to clarify.
For future reference, kernel upgrades and most major service interrupting maintenance takes place Fridays usually starting at 11PM. The reason for this is to give the maximum amount of time before the business week to recover in the event of severe problems with the procedure in question.
