I'm also in California. From here, it's 17 hops and ~85 ms to 148.78.243.30
which I think is close to the satellite uplink. (I used traceroute.)
If you want to measure satellite delay/position from here, you have to get
both a clean run from here to the base station and also an empty queue when
you get there.
>From a bit of poking around, the first seems unlikely. I've seen one
response at 85.226. but that's the only one under 86.
Satellite links are expensive, so I assume it will be hard to catch the
uplink queue empty.
