Topping tonight's list of things over which to get your knickers in a twist, Blizzard announced its weekly scheduled Tuesday maintenance window for US realms tonight. Some realms, under the cut, will have an extended maintenance period, ostensibly to complete the new server hardware additions that alleviate or resolve instance-launching errors. Good news for everyone -- even us, because maybe now we'll stop getting tips about it!

Maintenance will begin for most realms from Tuesday, September 1 at 3 AM PDT/6 AM EDT and conclude at 11 AM PDT/2 PM EDT.

For realms under the cut, extended maintenance will run from 12:01am PDT/3 AM EDT and end at approximately 11:59am PDT/2:59 PM EDT. In the meantime, you can check out our Cataclysm coverage, read up on Goblins or Worgen, emote beleaguered sighs to @WoWInsider on Twitter, or read the list of realms below, which may take you just as long.
