Yesterday's World of Warcraft patch listed that everyone would be able to create a Death Knight on any server, as long as they had a level 55+ character on their account. As it turns out though, that was not the case. The issue seemed to be somewhat random, where some players could create Death Knights on alternate servers while others could not.
In an attempt to resolve the issue, Blizzard performed rolling restarts this morning on all servers.
This, however, has not fully resolved the issue as of yet. Blizzard continues to evaluate the problem. Ten Ton Hammer will keep you updated as the story unfolds.
