It looks like the 'unkown' NAT proxies are going up pretty fast while other NATs go down. I got into the server, but I don't see it being overloaded or any obvious problem. I restarted probetest, let's see if it gets back to normal.
The restart seems to have solved the problem :)
Ok great, but, that means the "nat prober can't keep up" issue isn't a scalability bottleneck, it is a bug in the nat prober -- where sometimes it decides to stop probing, for reasons we don't understand?
If so, then better load balancing (https://gitlab.torproject.org/tpo/anti-censorship/team/-/issues/75) won't necessarily solve the issue.
Exactly, I'm not sure load balancing will solve the problem. We do have an issue for this specific problem, but haven't found what is causing it: https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snowf...
