The OP asked the question because the servers came back up after maintenance and then went back down for about 15 minutes. This had nothing to do with not knowing the servers were back up.
And the "server maintenance" news message (gone now, so can't link it) was updated to reflect that. I can't remember exact phrasing, but the message always includes a disclaimer that says if there is change of plans, the message will be updated. Which is exactly what happened - it was updated with new estimated time when servers will be back up.
OP's failure to read updated message does answer the "Who SCREWED up this time?" question rather well...
P.S... And then, we have
this thread too... Please notice the times.
