And how do you know this for sure? Have you monitored your line voltage
during an outage? Could yield some interesting results ...

Yes, at various times in the past I have done main voltage
monitoring professionally.

I don't do that now but the computer into which I am typing this
post is connected via a UPS that does record most mains voltage
variations -- sags, surges, spikes, outages, over-under voltage
and more.

And I too am in PG&E land -- not many miles south of Oakland.
