Ours did that Friday, and the servers aren't happy with it. I'm heading in now
to clean the mess up. Just out of curiosity, is there an actual term for this?
Does it sounds like BS? And, what do you think it did to the MicroVAXen...
We were told this was what had happened by the power company, does it sound
like BS or what?

New subject: What is it called when the 60hz line power becomes something else?
Sounds like BS to me! Power companies control their frequency VERY
closely. They frequently drop the voltage some under HEAVY laods like major
snow storms but I've never heard of them changing the frequency.
Besides the frequency shouldn't affect your computer, unless it's WAY off.

[MicroVAXes don't care]...
Ahh, good thing.
[What did it become?]
Who knows hertz and 60 volts. A serviceman across the hall did something
nasty to the transformer servicing the building when trying to re-route
power for a remodeling job. Yes, they're the same ones who cut our power
for 2 hours because 'We had UPSes, right?'
[When you get to the machine room, power line monitors etc.]
Don't make me laugh! Our machine room is a closet.
(Serious! I'll take a picture sometime!)
This is an ISP, not a national distribution center or something...
Oh, and who uses 400hz for line frequency?
I am officially here, by the way. CILCO is still yelling at A&B Construction
(Or whomever they were...) and my boss wants to go help. The machines
seemed to care more about halving the line voltage (Which I wasn't told
about) than the frequency change...

If the problem was caused by some inept serviceman mucking about with a
transformer, it is highly unlikely that there was any change in the
line frequency.

Oddly enough a lot of the HP stuff is spec'd to run on 50 to 440 Hz. I'm
not sure why unless it's to allow it to also be used in aircraft but that
doesn't seem likely.

Common AC distribution voltage on aircraft and other weight-is-important
vehicles.

Most of the Navy's computers used to be 400Hz onboard ship. I started out
as an Electrician onboard ship for 3 1/2 hellish years and had to work on
the Frequency converters. BIG water cooled suckers. Then I got smart and
switched over to computers. Just before I got smart and got out I was
working on a system that was about half 400Hz, so when we lost 400Hz, the
system would look like it was up, but wasn't.
