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.
What matters is the internet provider’s power.
I’ll give an example. A few years back there was a widespread blackout in California. My neighborhood had power, the adjacent neighborhood lost power for about a week. The cable service (Comcast/Xfinity) runs their lines on polls in this neighborhood, and I could see easily that they run from my neighborhood into that adjacent neighborhood. By the next day apparently their battery backup ran out, and my cable internet went down until that adjacent neighborhood got its power restored even though my power never went down.
