Seems that something has gone boom in the UO server, but not the forum
I am not sure , but the last time I heard, both the forum software and the UO Server were on the same machine, and the forum seems to be working.
FWIW - I was logged in this morning (Wednesday, July 11th) right up until I got the 1 minute warning about system restart. I didn't try again until later this afternoon, and the UO server seems to have been down for a while.
Hopefully, Ghost / Falkor are aware, and working on it.
