Hi Eric, This gives you the list of probes that have a last-mile median RTT (endpoint_type=LM&median__gte=495) higher than 495ms: https://ihr.iijlab.net/ihr/api/network_delay/?timebin=2021-04-21T00%3A15&endpoint_type=LM&median__gte=495 Looks like probes 55562 and 1000244 are both in US and ove

Hi Eric, Thanks for sharing that, I didn't know about that probe. I amazed by the stability of its last mile RTT (see attached graph LM36492). It looks like the probe is loosing connectivity to RIPE controllers once in a while, do you know if this is caused by starlink or is it other running

Another way is to setup a script listening at measurement id 7000. This logs all the probes connection/disconnection to RIPE controllers. Romain On 12/13/20 6:14 AM, Colin Johnston wrote: +one from me, asked that this functionality be added 5 years ago. On 12 Dec 2020, at 09:55, Gert Doerin

my non-scientific comparison: looking at RTTs in traceroutes the old v1 seems a msec slower. All are very stable Romain On 2/14/20 4:12 AM, Randy Bush wrote: if someone wants to compare, 4981 (a lovable old v1), 104, and 106 are on the same lan segment in the same pop with the same vr
