I have a standby generator that turns on within 10 seconds of an outage being detected. It burns natural gas and can run for days at a time.

If only.

I have a backup generator at home. When I had Comcast the internet would die within 20 minutes of an outage and would not return until the grid got up and running again.

I live in a place where power outages can be multi day events.

I have fios now - it stays up the whole time.
