With the exception of a few servers that will require additional maintenance until 4:00 p.m. EDT / 1:00 p.m. PDT, all of the servers are up and ready for action.
Last night Sacco talked about how he saw a gigantic dragon skeleton on his screen. I heard from him briefly this morning and he was rather incoherent, mumbling something about "trolls" and "lawlwut." So I have to believe the skeleton actually got him and is slowly devouring his brain.
In other news, the realms are up! ...in case you missed that part.
Go forth and enjoy Azeroth
