Update: Blizzard addressed the issues and explained what steps they took, with two major fixes starting three hours ago.
About 3 hours ago, we deployed increased capacity to address the initial peformance issues.
About 15 minutes ago, we deployed a change that spread out players a bit more, to reduce congestion and latency out in the world.
We’re continuing to monitor conditions on all realms and we’re working urgently on issues as they arise.
It seems a lot of players went into the mists with the launch of Classic, and the servers are having a bit of trouble keeping up! Blizzard are working on the issues US and EU servers are facing and hope to have them resolved soon.
The Mists of Pandaria Classic launch was very popular!
We’re working quickly to resolve server capacity and stability issues for some US and EU Classic Realms. We don’t currently have an ETA, but we hope to have it resolved shortly.
