Our new EQ2 Community Manager Roxxlyy posted an update yesterday afternoon indicating that the issue preventing many players from downloading or updating EverQuest II with the patcher should now be resolved. From the EQ2 Forums:
Login and patching issues are believed to be resolved at this time! Please let us know if you are continuing to see any persistent issues.
I got a failed to create zone, please run the patcher message, but it was not repeated.
Cannot log in – says Skyfire not found. Was working just fine earlier.
