This week, maintenance is extended for 22 US realms that need additional database and hardware maintenance. These realms will be going offline at 3:00 AM PDT, while the rest of the realms will be going offline at 5:00 AM PDT as usual. So if you play on any of the following realms, prepare to loose a couple of hours of playtime: Alexstrasza, Alleria, Balnazzar, Blackhand, Cenarion Circle, Cenarius, Cho'gall, Destromath, Dethecus, Garona, Gorgonnash, Gul'dan, Hellscream, Hyjal, Illidan, Kael'thas, Kirin Tor, Lightbringer, Spinebreaker, Stormreaver, Uther, and Whisperwind.
