Power failure in a data center? Heads can roll for something like that.
Last time I saw that happen was at a huge DC in the UK; down for 30 minutes and when everything did come back up, many servers had to have their power supplies replaced due to trauma.
But if I may ask ... if a power supply ... then how was the home page able to continue to work?
It's db driven. Even if cached.
I am simply curious. Not challenging the reason ... nor doubting you.
