Due to a power failure the authentication server and some realms are currently offline. At this time it is not possible to log in to any realm, forum, or account management. Any player who is currently logged in will not be logged out, but if they do log out they will not be able to log back in until the issue is resolved.

The following realms are currently offline due to this:
Agamaggan, Aggramar, Al'Akir, Arathor, Argent Dawn, Aszune, Azjol-Nerub, Bladefist, Bloodhoof, Bloodscalp, Burning Blade, Burning Legion, Crushridge, Daggerspine, Deathwing, Doomhammer, Draenor, Dragonblight, Dragonmaw, Dunemaul, Emerald Dream, Sunstrider, Twilight's Hammer, Warsong, Zenedar

12:30 CET
We currently expect everything to be online within the next couple of hours.

Update 14:15 CET
Authentication is now online again, but may be slow for a while. Some realms will have about 1 hour extended downtime and be online again around 15:00.

The following realms are currently offline:
Argent Dawn, Bladefist, Bloodscalp, Burning Blade, Burning Legion, Crushridge, Daggerspine, Deathwing, Draenor, Dragonmaw, Dunemaul

Update 15:00 CET
All realms should be back up again. We apologise for the great inconvenience this has undoubtedly caused everyone, and thank you for your patience while we resolved the matter.
