Strange since it's a downloadable map...
I'm gonna try the map and see if it's a universal problem. In the meantime try disconnecting and reconnecting your internet and turning off water reflection.
EDIT: Yup, can't connect to it ether so it's down. You might have to wait a few days or so. It'll probably take another server restart for it to work again.
Reset your characters homes via the User Panel if you have any characters stuck in that map.
