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.
Comcast might work. Most of their infrastructure has small battery backups, but will eventually go down after a few hours. For long term outages they will send out techs to hook up generators to bring the infrastructure back online. But for outages that last for less than a day, the internet will stop working after a few hours.
