If you've been following the WoW Customer Service forum [that's where lag posts go] it's been blowing up like crazy the past 72 hours and the CMs were locking threads left and right because it was out of hand. This morning about 72 realms were down for emergency maintenance which ended earlier than Blizzard had expected. I'm on Kil'jaeden which was getting beaten down by the character selection screen, loading screen, and vendor bosses. Tonight it feels good so far...maybe Blizzard actually fixed what they broke.
