But what is going on then with:

This probe is within AS15435 and when I list all probes in that AS it is shown, but I cannot add it to a measurement, it is rejected.

Using a curl request to:

stat.ripe.net/data/atlas-probes/data.json?resouce=15435

shows this probe, with a tag “is_public” : false

and I cannot access this probe’s info via the link above, I cannot add it to a measurement and I cannot access any data it collects.

How does this rhyme to that non-public “probes are therefore contributing very nearly
