See https://ring.nlnog.net/.Similarly you might reach out to RIPE and inquire if they are interested in adding this functionality to their Atlas Probes et al.
RIPE Atlas is a bit "different" in that you need credits to trigger something on Atlas. And Atlas already implements traceroute, incl. Paris Traceroute. That means, in fact (if you have credits) you can already reverse traceroute from an Atlas Probe to yourself (and other places on the internet).
But, you are raising in interesting point, which we have thought about but dismissed. But feedback from the operational community on this would be valuable. Our reverse traceroute currently restricts the server to trace back to the issuing client. We did this for security reasons. The question was "why should anybody on the internet be able to do a traceroute from my server to a destination of choice?". Lifting this restriction would allow a functionality similar to "https://downforeveryoneorjustme.com/". But, somebody might use your server for this. How do people feel about this? Restrict the reverse traceroute operation to be done back to the source or allow it more freely to go anywhere?
Best, Rolf
