Our server hoster is going to be doing maintenace on the server node that we're currently a part of on the 11th of this month. They say the server is going to be down for a few hours, and then it should be back up at a different IP address. The fenix.mymcnode.com IP address theoretically should continue to work without issue. However the physical IP address 18.104.22.168 will change.
More information will come once I get ahold of it.
Note, this DOES NOT mean a reset, restart, or even a rollback. All of your stuff should be saved.
