"Error 34200 when trying to retrieve character"

GameAccountLogon Failure 34200 error - game_utility_server_no_server

Logon is correct, it will throw a different error if I dont use the right password. It gets through the Connecting and Authenticating steps, but balks on the last checkbox. I dont have any characters yet.

Anyone else seeing this, is this a general "Battle.net hates you" error?
