If you're in a rural area (and heck, even in an urban era) the primary ISP of a region dropping is likely to cause a lot of congestion from cellphones falling back to the operator network.

I found it quite absurd that Spectrum (my cable operator) wants to sell me a modem with integrated 5G/4G backup knowing that as soon as the cable plant drops, hundreds of local phones are going to congest the network as well and my "Invincible WiFi(tm)" will end up dead as a dodo.

I'll just throw a Peplink up and throw the cable and Starlink into it and run that as my load balancer.
