Just before lunch (12.06 to be precise) my domain server rebooted itself, first I realised was that at the exact moment it rebooted a class was trying to logon. When I went to the server room (storecupboard) to see what had happened the UPS was showing as running on battery power but the computer was displaying running on ac power and charging.
Did anyone else's server reboot today - sophos? I've checked logs and can't find anything relevant. There was no power cut but if there was the server would run on the ups.
Anyone any ideas?
