OK, let's get it over with
My power was out from 4:10 PM Thursday through 12:00 AM Friday.
My first act, after making sure the computers were off (the UPS doesn't last more than about 10 minutes) was to shut the main breaker.
I was one of few people with phone service in my area. My DSL line is copper. My wife's home-office fax line apparently is over fiber--it was out of service. (No dial tone, and when I called it, I got a ring and then a fast busy.) I'll keep my copper, thank you.
