Last night on 4 different occasions I've joined a server only to play for a few minutes and then the server would shutdown. Im not sure if it was restarting as I waited for a minute but did not see it return to the server browser screen so I would join a new server. Me and a friend jumped 3 times between servers until we found one that didn't restart. This is not a disconnect on my part because I was with friends who also confirmed the server went down. It seems most of the servers restart/shutdown around the same time. There needs to be at least one warning before a server decides to restart.
