The reboot of the server failed due to an unforeseen firmware or hardware problem, which required manual intervention and physical access. The problem was resolved at 06:25 UTC (08:25 CEST), and the MUD and related services were back up at 06:33 UTC (08:33 CEST).
There will be a reboot just before 18:05 UTC (20:05 CEST) today, which will involve not just the MUD, but also the website and FTP access. The OS kernel is being upgraded.
The MUD should be back up before 18:30 UTC (20:30 CEST), probably around 18:15 UTC (20:15 CEST).
