@geerlingguy: Consider checking out some global latency comparisons between StarLink and cable. I believe their long-term plan is to have the satellites route traffic between themselves using space lasers rather than hit a ground station and traverse undersea cables and the like.
Not sure if they have that fully implemented yet, but might be interesting looking at the path and latency traffic to .au or Asia or Africa takes on Starlink vs cable. A couple factors may come into play: "as the crow flies" and light speed in vacuum vs glass.
I know Evi Nemeth (RIP) talking on the CAIDA project showed some nice graphs of the "speed of light cone" re: latencies vs. geography.

- tsimionescu 5y agoThe lasers are more a nice idea than a plan. It's entirely possible they are not doable with realistic technology, given the speeds and other constraints of space, even in LEO. They are certainly not going to be there in the near future, anyway.
- relativ575 5y agoNot just an idea anymore. They've started experimenting with it since last year. Gwynne Shotwell said in April that third generation, yes third generation, of laser intersatellite links would be launched in "the next few months": https://spacenews.com/spacex-adds-to-latest-funding-round/ https://spacenews.com/spacex-adds-to-latest-funding-round/
- matmatmatmat 5y agoYeap, and full self-driving is coming at the end of this year.
- shaklee3 5y agoIt's an idea. They have not been demonstrated successfully.
