Try to log in, authenticates then disconnects

Hello,

I was disconnected from the server while waiting for a random, and when I tried to log back in it tries to connect, says it's authenticated, says success then goes to the character page and immediately says "You have been disconnected from the server".

The realm status page indicates Blackrock is not down, I'm not sure if this is an isolated or a more widespread problem. Is anyone else having this issue?
