Update: Server is back now, thanks for waiting it out!
At the end of the current game month (currently due in about 1.5 hours) the server will be going down for a restart and some software updates.
I'll try to work as fast as possible and will get the server running again as soon as I can. I'm estimating about 30 minutes downtime but it could take up to an hour. I'll update this post if anything changes
