In case you haven't noticed, some realms in Blizzard's World of Warcraft have been suffering from erratic connection speeds and frequent disconnections. Authorities are hard at work, but several servers had to be taken down for maintenance.

According to blue poster Drysc at the WoW forums, here are the World of Warcraft realms that went down:

• Aman'Thul
• Barthilas
• Blackrock
• Caelestrasz
• Dath'Remar
• Dreadmaul
• Frostmourne
• Frostwolf
• Khaz'goroth
• Kil'Jaeden
• Kilrogg
• Nagrand
• Ner'zhul
• Proudmoore
• Sen'Jin
• Silver Hand
• Thaurissan
• Tichondrius
• Vek'nilash

It's been a few hours since the switch was turned off, but continuous latency issues and disconnections pushed Blizzard to extend the urgent server maintenance. We're sure to keep tabs, so check back for updates!
