Well they finally managed to do it. I noticed high ping about a hour ago while in a BG slowly going up like a Ddos and they finally go it done. I am very impressed and somewhat scurred seeing as Blizzards servers are amazing.
Edit: Login servers are fine individual servers are going off and on. They are trying to come online but it seems that the dos is too much for them. I literally just switched to Skyrim 5 minutes before this happened. I feel awful for anyone who was in a heroic encounter.
