When I was in Fort Worth, my UPS would cut in and out like a flip-flop
so bad was the supply during hot spells.
(Every time the whole streets air-cons cut in at the same or similar
time it would cause a major drop in line voltage. I gave my UPS logs to
a TX Employee who lived in our street and they had engineers out the
next day to change a faulty transformer in the neighbourhood. Everyone
had noticed the lights dip but didn't realise the power was dropping
that much. A few had noticed computers rebooting for no reason but
didn't make the connection).
