Not sure exactly how useful that would be, but the latency is low: 0.01 seconds to cross the width of the USA.
A round trip packet from NY to SF takes 0.05 seconds, a fifth of the speed. Fibre is quick, but not as quick as radio.
There’s about 1400 bytes usable in a TCP packet, versus the 1800 symbols per second over shortwave. Lots of TCP packets can be exchanged per second.
I don’t see the value proposition.
The real takeaway here is that we are all bad at storing the kind of knowledge you’ll find in a troubleshooting post.
Perhaps there can be a Lemmy instance that scrapes and mirrors troubleshooting posts across other instances.
