I was working from home (we had no offices yet) and my cable Internet got cut off. My only back up was a serial cable to a 2G Nokia 9000i. I had to re-encode a chunk of the music catalog at 8kbps so I could test it from home before I pushed the code to production.
Psychoacoustic compression is a miracle.
BTW, an interesting thing is that some/most carriers allow you to use CSD/HSCSD over 3G these days, and you can establish data CSD connection between two phone numbers, yielding essentially a dedicated L2 pipe which isn't routed over internet. Can have much lower latency and jitter if that's what you need. Some specialized telemetry is still using that, however as 3G is slowly getting phased out, it will probably have to change.
Still have an entire territory where everything is satellite fed (Nunavut), including its capital.
> Northwestel, one of biggest internet service providers in the North, said it provides broadband service for all Nunavut communities using Telesat's Telestar 19 VANTAGE high-throughput satellite. After the satellite was deployed in July 2018, Northwestel said it would significantly improve broadband connectivity in the territory, increasing speeds to 15 megabits per second.

Interestingly, the same satellite (but different transponders) probably supplies internet to a good chunk of transatlantic voyages between US/Can and Europe: https://www.telesat.com/wp-content/uploads/2022/11/Telstar-1...
