We are getting transferred to a new computer with our current host, it will change our base (numbered) IP address, but it will also save our host money and keep him in business.
You may have also noticed before it happened that play.pokemonserver.net worked. It will also work after the transfer.
There will also be another bout of (shorter) downtime after the transfer, where I plan to update us to 1.5.2 and that will surely break plugins, particularly Runecraft (again). So please bear with us today, and lets all get through this with little interference.
