Edit: James here, offering my 'Private Server' up. It's nothing more than my old pc and an unblocked port. the IP is 206.255.67.216:7777
Well, the server's not really down, per se, but Terraria just updated, and the server will more than likely not be the same version as yours. That, and we'll probably need to wait for the next TShock update as well.
We'll be back as soon as possible!
UPDATE: Server has been updated to the current version, but we're keeping it off for now, until TShock is updated. This is for the protection of the server, so I hope you all understand.
