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 entirely depends on whether Xfinity has backup power for all of the devices upstream from you, how well those devices are maintained, and how much fuel they have.
In my experience, cell towers are generally pretty reliable and seem to have first priority. In an extended power outage the generators powering individual neighborhoods seem to run out of fuel after a few hours.
