Maybe atlas could come in handy here?

Bengt,

in fact some of our beta testers for "User Defined Measurements" thought so too and started measurements. At the moment the maximum number of probes they can use per measurement is 10. So this is not entirely representative. Plots are "dnsmon" style, so green=good & red=bad. There is more green than red, that is encouraging. Even more encouraging is that probe #899 actually got connectivity today. Congratulations to AS39759 from the beatiful Republic of San Marino!

We will work to make a more representative measurement as soon as possible.

Actually, I think this debogonizing scenario is the kind of situation where "compound" measurements can make sense as probes number 929, 843 and 325 depicted in these graphs and belonging to ASN 48954, 15764 and 20825 respectively, dont seem to be able to ping 128.0.0.1, but, 128.0.24.1 pingable address, on the other hand, is fully available from all the probes from ASN 31027, 6750, 5539, 8365, 42760, 25538, 35706, 345954, 2108 and 719. If same probes could conduct pings to both prefixes we could get an even more accurate picture of the portion of the network Atlas covers and monitors. Back to the routing-wg topic, as Alex Le Heux is CCd, I think at least AS 48954, 15764 and 20825 contacts can be already be notified on their seemingly outdated filtering, as those red bands are "horizontal" enough to do so.
