In isolated area backup is essential.
The local communications company that provides Internet, phone and a TV DVR service via fiber cable has a battery backup on the converter.
I have my router on UPS as well as one of my cordless phones.
They would keep communication for 20 min if needs be. However I have the auto start generator that comes on automatically in five seconds.
In the last two years we have had a couple of episodes of severe weather causing some serious problems.
This is the only residence that can keep communication with the outside world during these events, and has been useful.
And yes, we could watch Netflix!
We were watching a movie with friends during a power cut last summer in a storm.
Everything is on a UPS except the power amps. The generator came on quick enough before the power supply caps in the amps were completely exhausted!
