Incredibly, my fiber internet never went down the entire time. That part of my infrastructure is buried and they back it all up with proper generators.
I'm in the affected area. The contractors that they used to install the last mile fiber didn't do a great job. They not only damaged other cables like the coax but "buried" isn't how I'd describe the fiber. In the easements the fiber is only a couple inches below ground at most, in some places it was above ground and I had to bury it myself.
I do wish Comcast (and Tmobile) would use generators instead of battery backups. We get about 4 hours of internet when the power is out and I run the home router off of a generator.
