An emergency patch that was announced last night.
I don't have a problem with the servers coming down to fix problems but please, FOR THE LOVE OF GOD, pick a time and stick with it. Two weeks running downtime was postponed, and now the emergency patch has been delayed twice (was to be 11am, then 2pm and now it's 3.30pm).
All of this is making them look like a bunch of complete amateurs, as far as I am concerned.
(And of course that will make them lose sleep, not)
So yes it needs to be fixed, but Bioware is damaging their reputation every time stuff like this happens.
