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.
I’m a lineman for Comcast, there’s definitely power backup for every node. How long they run depends on the current draw of the system, but they’re usually a couple of hours at least. We get dispatched to hook up generators when the batteries get low
If only.
I have a backup generator at home. When I had Comcast the internet would die within 20 minutes of an outage and would not return until the grid got up and running again.
I live in a place where power outages can be multi day events.
I have fios now - it stays up the whole time.
