This just in from developer Mose:

I will be going to assembly tomorrow so the server will go down again. I might host the
server when I’m there, but don’t count on it. I will post the changed ip when and if I decide to run the server there.

PS. In the unlikely case there are any Finnish players who are attending assembly this year they can post a reply in this thread and I will PM you where my computer place is located. I just might give you something special in game if you come to say hi.

If the server is not hosted at the assembly, expected down time if four days.
