Our cable DOCSIS isp in our neighbourhood was down for a whole week. Each day the calls and a tech visit on prem were assuring us "this is a top tier priority outage, we have crews on it 24/7", yet in the neighbourhood, not a technician in sight.
Finally 7 days in a crew showed up in the street measuring each street cabinet. They were able to pinpoint the fault to a house 2 blocks down, where they told us a partial cable cut apparently had signal from their powerline flooding the coax signal. Once they decoupled that premise, signal in the area went back to normal.
We were lucky in that we had a DOCSIS 3.1 that tries to downregulate modulations when cable noise is present, so instead of going to 0 internet for a week like the older DOCSIS installs, our usual 500/30 Mbps still managed 0.1 - 3 Mbps up, so things like mail could still eventually get through.
Now looking into Starlink as a backup, as until they run fiber here, there is little alternative (besides vdsl, which is its own nightmare)
