Hi Robert, weirdly, some of the SW probes are showing as "online" but do not provide any measurements results [event the Built-in ones], such as your mentioned 1000030 [Latest data point shown is from 2019-12-17 11:57 UTC] Also for example measurement https://atlas.ripe.net/measurements/23955368/ shows 18 out of 71 SW probes were online [at the moment when I created the measurement] but never provided any results. In https://atlas.ripe.net/measurements/23962519/ I requested all probes with tag system-software, you can see how many probes are Online while not providing any results. What I wanted to point out - I run SW probe 1000069 in Turris Omnia router and I noticed the same behavior - after router restart the SW probe goes online and looks fine, but does not send any results, until I restart the ATLAS process manually, then it runs fine until next router's reboot / power cycle.

To be fair the v1 and v2 (ID<=5000) are 9+ years old tiny embedded devices, their capabilities are nowhere close to anything else one runs Linux on nowadays.
Note that our team is also analysing the similarities/differences, but if someone else also wants to look, these are good candidates (same AS, same prefix, approximately same location):
https://atlas.ripe.net/probes/1000030/ (sw) https://atlas.ripe.net/probes/28270/ (v3)
or:
https://atlas.ripe.net/probes/1000041/ (sw) https://atlas.ripe.net/probes/54558/ (v4)
Cheers, Robert

my non-scientific comparison: looking at RTTs in traceroutes the old v1 seems a msec slower. All are very stable

if someone wants to compare, 4981 (a lovable old v1), 1000004, and 1000006 are on the same lan segment in the same pop with the same vrrp exit etc.
