Well, ladies and gentlemen, we have some good news and we have some bad news.
The good news: Servers are coming back up, at least for those in the United States! You can log on and enjoy World of Warcraft again, ahead of the previously announced 5 p.m. PST time.
The bad news: Some dragon-ish rapscallion has totally shattered the world over the course of the last 12 hours or so. Whoops.
