Game froze on my home server, Leviathan.
Restarted. and was 528th in queue.
Went to another datacenter, 28th in queue.
Game froze at the end of a quest as it has been doing.
Restarted, and went to another datacenter, no queue, logged in immedately.
Played for about 30 minutes and game crashed at quest completion.

There is far more going on here than a population issue.
