So it seems it will take some time for bukkit to get update, the temporary server will continue running, and the old server will continue running, and I've got everything prepared, so as soon as bukkit gets updated (assuming I'm at my computer) I'll be able to start the new permanent server. But I won't be able to make it home until 4 PM GMT+1, so this is the earliest possible time the permanent minecraft server will go up.
Once I've got the new server set up, the old server will be accessible at simplicitypvp.net:27027. and you will still be able to have your stuff moved over.
