Hi Eric,
This gives you the list of probes that have a last-mile median RTT
(endpoint_type=LM&median__gte=495) higher than 495ms:
https://ihr.iijlab.net/ihr/api/network_delay/?timebin=2021-04-21T00%3A15&endpoint_type=LM&median__gte=495
Looks like probes 55562 and 1000244 are both in US and over satellite.
I don't see the probes tagged with 'Satellite' but some of these probes
are <200ms to the K-root...

Hello all,
I am running what I believe to be the only probe on a Starlink satellite
connection right now:

Is anyone aware of a list of probe ID numbers which are definitively
known to be on some form of satellite-based access technology? I am
thinking of, for instance, sites on consumer grade geostationary VSATs,
more serious VSATs, or in island nations which are not known to have any
submarine cables.
The reason why I am searching for such a list is that I intend to
consume some of my accumulated credits to run periodic one-off
measurements of latency, traceroutes and other things to quantify
improvements in satellite based latency and other performance metrics
over time. And to quantify what it looks like when an ISP previously
dependent on geostationary (min 495ms latency) gains access to either
terrestrial/submarine fiber, or a lower latency low earth orbit based
service.
The best information I can find right now is to manually pick probes
which never show below geostationary latency to a first hop in any
traceroute, and are located on the probes map in certain island
locations. It's a bit more time consuming to manually search for probes
in continental locations which are on a VSAT (for instance if anyone
knows of a probe on a VSAT terminal in a remote part of Wyoming, USA,
let me know...).
