So no indication as to what happend? or if any more damage was done?
Pure speculation but from what people are describing as happening ie the server coming online and going back offline yet still showing large chunks of population playing on it - I'd say it's a routing issue between Hunter's ISP and the Login Server ISP. Something must be impacting those routes so it may not show on the login server when the routes are down/congested but it wouldn't impact people's ability to play that are already logged in.
Hence it isn't a server issue.
