I don't know about anyone else, but last night (Saturday) around 1930 to 2030 on Blackhand I was getting major lag, CTD's (with and without XFire up, which seem's to cause it too). I would see a Quest guy just disappear and come back in 10 minutes (unless this is part of something on the Alliance side I've never seen the Horde side do). But I had like 3 'WoW' CTD's in 10 minutes.(probably about 5-6 in an hours time) This was Blackhand. Running Cosmos.
