Wow. One can only dream about such a stable commercial supply. Since the
event I wrote about, we already have had one hit big enough to trigger
the generator. It is the rare month the generator does not earn its
keep. The UPS log of minor hits is quite lengthy.    

Our system, by the way, is totally automated.

The UPS system did fail once during a routine weekly test due to a
defective battery. That's two full outages in six years. Compare to
dozens, perhaps hundreds of times it worked like a charm and kept us
running.

Subject: An unexpected lights out operation

I worked for  four vendors - ITEL, NAS, BASF/Comparex and Amdahl from
1978 to 1992.  I have
never seen a situation in which the presence of a UPS actually improved
matters - they are a
much greater source of problems than the public electricity supply.  My
definition (below) is
the honest result of years of experience.

And I HAVE actually seen a customer executive cry.
