The opening announcement just told us all that realms are coming back online now. All the realms will be completely back up by 10:45pm EST / 7:45pm PST. Realms have been down today for an overly-extended maintenance period.
There will be an in-game mail sent to all players concerning the mail issues today. For those that are unaware, all mail that was in the mailbox prior to the downtime today was gone when the servers came up for a brief time today. We have covered everything we currently know about this. The mail will be reimbursed.
Let's all say a silent prayer that this is not how the next couple of days look. I don't know about all of you, but I actually want to play Wrath of the Lich King when it's released.
Update 11:50pm EST - All the realms are coming back up. We'll have more on fallout of this tonight and tomorrow.
Update 11:30pm EST - We've sent word to our contact at Blizzard asking for more information about today's issues. We'll let you know the response we get.
All previous updates are being kept after the break, check there to see a log of what's been going on.
