I know its super early but we might forget later. Due to issues we were having with our Minecraft server host, we are doing a bit of an IP address switcharoo.
So, will this affect our fellow players? Not really. When the server is ready for players again, you shouldnt have anything change. All inventory (including contents of your enderchest) should be there. Achievements, towns and builds should also be unchanged.
However, there will be some downtime for a few hours while we swap things over. Please have patience and thank you for your understanding. Icy has been a helpful bean during this time, moving the Frostcraft world onto better (and faster) things.
