[Starlink] musk: 28ms median latency on starlink

[J Pan]

it's the user dish (ut) to pop (or ip gateway more precisely, not the
ground station, collocated with the user's home pop) latency. thanks
for the ripe atlas probes---we are hosting and using them too---the
downside of ripe atlas is that it's mostly user hosted (so not always
online) and the space and time granularity of the measurements that
can be done for research

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

There was also a recent 3rd party report on that (see Figure 1): https://www.netforecast.com/wp-content/uploads/NFR5150_NetForecast-ISP-Performance-Report-2024.pdf.
