The server's having issues. The hosting situation is relatively unstable it seems, and there hasn't been any news of it being fixed in the near future. Hopefully we'll know more of what's up soon.
Most of this information isn't posted on the forum, you'd have to ask admins in-game about it. Maybe we can badger them to give more frequent updates here on the forum. Brief updates. Since very few people actually come here anyway, it might just end up being a waste of time.
