On top of that, a lot of sites use fiber for the backhaul. Another major failure point. Even if the site has generator backup, the CIC cabinets the phone company use run on battery, so even a prolonged simple power outage can render the site useless. Never mind the risk of fiber damage or anything else.
Here in Florida, my neighborhood cable provider (no fiber) relies on battery back up for the cable amps. There is barely 4 hours of battery, These batteries get punished whenever there is a power outage (frequently). I think this is the future of cable and fiber. The battery capacity will never be like the old days when a CO had a couple days of 48VDC and massive generator capacity to run indefinitely. The failures will be the mid points, fiber repeaters, multiplexers etc in the field.
