Some people suggested adding {2,3,4,5}G as another fallback. This often fails because the cell tower is connected to the same cables. Or the backbone burns down. Or the connection between the datacenters fails (see recent AWS failures). Or coworker is mad... It is good to prevent failures. But autonomous local systems shall remain (basically) usable for some time. And if the local system is a paper, that's at least something. We've also ABS, ESP and ASR in cars. We still close the seatbelts.
