Patch 3.1.1a, which we previously covered last week, will be coming during tomorrow’s extended maintenance. This is according to a small update Crygil gave this evening.
While we don’t have the full patch notes yet, Patch 3.1.1a will just correct small issues that cannot be hot-fixed into the game. Notably, the tooltip to the Paladin’s Exorcism ability will be updated to reflect that it cannot be used on players.
Realms will be down from 3:00 a.m. PDT / 6:00 a.m. EDT until 11:00 a.m. PDT / 2:00 p.m. EDT. We’ll let you know when they’re up, and if there will be any additional extended maintenance.

Today’s epic maintenance to apply patch 3.1, which has stretched from 1 AM for some realms and 3 AM for others, has been additionally extended. Originally, the realms were supposed to go live at 11 AM PDT; that time has come and gone, and been pushed back a few times.
The latest update, posted to the Breaking News box a few minutes ago, is that they do not currently have an ETA on when the realms will be up, and they’ll give us some more information at about 2 PM PDT, which is in 45 minutes or so.
Update 5:15 p.m. EDT: The realms continue to be down, with the in-game message now telling us that there will be an announcement at 6:00 p.m. EDT letting us all know more information.
Update 6:15 p.m. EDT: Maintenance is continuing on all realms. There is no time frame given as to when the realms will be back up, however there will be an additional announcement at 7:00 p.m. EDT. Stay tuned to WoW Insider for more information. Additionally, the official forums and account management appear to be intermittently down now as well.
