We had a couple of momentary losses of power here in Clifton overnight. Once at about 3.30, and again at about 4.30.
It set off loads of house alarms and reset our alarm clock (which has battery backup... but that doesn't work if it's got the DC jack plugged into it )
However, the media centre PC has an uptime this morning of 97 days and the NAS box 101 days. The router did reset, though.
Interesting to see what the PSUs of different devices are like...
