Hello!
I wanted to create this post to see if I can get an answer, as google seems to give mixed results. This winter, I was thinking of getting a small generator incase our power goes out. We live in a rural area, so I have propane for heat, but was more worried about keeping devices charged and some lights.
I was curious if we had a power outage, if I powered my modem- would I still be able to have internet access? We have Xfinity but I wasn’t sure if there is a total power outage, if the internet would go down either until the local system is brought back up or if it had batteries/self generators so the network stays up during an outage.
It depends on your ISP but it’s likely.
I have a huge propane generator for extended outages… The UPS systems I have now will keep things powered for over 3 hours with full load, but I have non-critical devices power off after 10 minutes and that extends the batteries to ~12 hours.
Still, if the power is out for 40 minutes, the generator kicks on and takes over. Internet stays up and with two 1000 gal tanks, I can run the generator for months without refueling at full load. Having the extended runtime batteries allows for generator maintenance windows and such.
