Could it have been a simple case of a spike on mains power?
I suppose, but there were no messages from my UPS which
generally whines about stuff like that. Maybe it was
a test of an alien EMP device :-).
I guess I'll see if it happens again, or was just a one time thing.
I have more problems from sags than spikes. That is why I use at line
conditioners (like Tripp Lite LC line) or UPS with line conditioning
(prevents constant switching to batteries when a sag drops the voltage
below 90v). Notebooks tend not to be affected too much, but switches
and APs reset. The utility (DTE) says I am 'within specs', but you can
see incandescent bulbs dim when anything heavy comes on line. And my
kill-a-watt reports the voltage drops.
I had a wireless extender plugged directly into a regular surge
protector, and my notebook would regularly drop its WiFi connection then
have to reassociate and release its address. I had to get a LC just for
the one device.
