Blizzard has apologized for the spotty launch of Diablo 3. It has also announced it is delaying the launch of the game's real money auction house. It will be open for business later than the originally announced May 22 date.
"We sincerely regret that your crusade to bring down the Lord of Terror was thwarted not by mobs of demons, but by mortal infrastructure," Blizzard said in a post on its forums. "As many of you are aware, technical issues occurring within hours after the game's launch led to players experiencing error messages and difficulty logging in. These issues cropped up again last night for the Americas and Europe servers. Despite very aggressive projections, our preparations for the launch of the game did not go far enough."
Blizzard says it is monitoring Diablo 3 "24/7," and promises it has applied "several optimizations." Right now, the servers seem to be running well.
We don't know when the auction house will open, but Blizzard promises more details soon.
