Computers run 24 X 7 (bout 32,000 hours run time a year) and are hard
wired together with Cat 5 cable.
No problems since going to UPSs with line conditioning.

Last Fall, this one had over 57 transfers to the UPS over 3 months
including 3 brown outs, one black out (quite a few hours), and the
rest was line noise.

I too had at least that many momentary high line-noise and brownout shifts
to APC since Hurricane Isabel last September. But my computer runs in real
time, so it could only get 8,736 hrs in a year if I left it on all the time
:-)
