In my experience, if you get internal error for a longer time it's the server you logged off at that doesn't feel too well ie server has crashed, but not so badly that the client loader detects it and sends you to Another server.
A special case of this is if you, by exiting a mothership, happen to end up outside in "Deep space" and you relog rather than get "sucked back" into the mothership.
If you get it for a longer time and it's not space, you could write where you are, maybe there are other people who also are locked-out...
