[Starlink] 42 petabytes/day and ...

[Spencer Sevilla]

Yeah I forget exactly where/when, but approx. five years ago there was a
LEO workshop at some big academic networking conference (maybe sigcomm?)
and I noticed that almost all the papers used NY-London latency as their
primary evaluation metric. One of the papers even proposed some wacky multi
hop system using commercial planes that were likely to be reliably
scheduled on the route. Confused the hell out of me (reading these papers
with an eye towards rural access) until my colleague pointed out the likely
funders of the research and their priorities 😂
