Infinite Loading Screen Bug

Just hit me for the first time today, and I have not been able to do anything for several hours. Doesn't matter where I try to reach, there is a high chance that I will be stuck indefinitely on a loading screen. I was even prevented from logging on to a character once - I selected a character, but was returned to the login menu with the message "authentication failed for instance transfer" or similar.

Australian gateway, and I don't think it has anything to do with lab enchants, as I have not changed them for at least a week now.
