We don't have an ETA for when login will again be stable for all players, but we'll provide updates as they become available.
Thanks again!
-----We're aware that players are currently receiving a variety of error messages when attempting to access the Mists of Pandaria beta. We're looking into those issues at this time and are working to resolve them as quickly as possible.
We hope to have beta participants back online and testing later this evening. As further updates become available, we'll provide them in this thread.
Thanks for your patience!
