Love this tool! I upgraded to premium so that I could see which apps are the most chattiest... it turns out to be Tailscale. It connects to a lot of random places across the whole(!) world. See: https://imgur.com/a/Gc5pnih

Any reason for this behaviour?

They use those relay servers for handling NAT issues, and figuring out which one has the lowest latency requires them to ping them all.

That said you can run your own one if you need to.

My semi-educated guess is verifying server status to know which endpoints are available.
