<p class="MsoNormal"><span style="font-size:14.0pt">First
question is what was the test destination? From the CPE to a
ground station or to something at a peering point or on the
internet? I would assume either to ground station or 1 hop
beyond (peering point)… That way we can do apples-to-apples
comparisons, so to speak. <o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:14.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:14.0pt">In any case,
there is a lot of good 3<sup>rd</sup> party data out there
for this. First is RIPE Atlas. I helped get a lot of probes
deployed in the US and there are now 78 probes connected
globally (roughly 30 would be sufficient to call it
statistically significant): <a

https://atlas.ripe.net/probes/public?sort=-id&toggle=all&page_size=100&search=AS14593&page=1&status=1</a>.
So if you know how to pull data from Atlas, it is there for
you to analyze… (see
<a href="https://atlas.ripe.net/docs/apis/rest-api-manual/"

<p class="MsoNormal"><span style="font-size:14.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:14.0pt">There is
also this recent report that used a hardware probe connected
over ethernet:

<p class="MsoNormal"><span style="font-size:14.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:14.0pt">Another
approach similar to accessing RIPE Atlas data would be to
get the Cloudflare AIM data from M-Lab – see

There was also a recent 3<sup>rd</sup> party report on that
(see Figure 1):

<p>I was having the same question of where are the test destinations
when talking about 28ms latencies.</p>
<p>For my part, when I read latency evaluations expressed in
milliseconds of RTT (round-trip time) I kind of assume we talk
about using the tool of the website speedtest.net. It is a very
approximate number but I think it is understood by many people.
That speedtest.net website has some server participants. The test
indicates where is situated the particular server in use.</p>
<p>Of course, ideally, spacex should tell precisely how they
obtained that latency number (28ms), but I doubt they'll ever get
into that kind of detail. It's as if I asked them to tell what
algorithm is behind xai, or so.</p>
