Unable to log in on any MoP character after patch

After the MoP realms came back online after downtime today I’m unable to log in to any of my characters. The loading screen will progress to around 90% complete then either I’m disconnected or I get a character not found error. This happens with all addons turned off, and I’ve tried both the merged server and legacy servers with the same results.

Having this exact same issue. Have restarted battlenet client, PC, and tried a scan & repair all with no change. Addons are off, doesn’t matter what level toon or location it’s in. :frowning:
