Better QA endpoints #135

Open jimaek opened 1 year ago

jimaek commented 1 year ago

The issue keeps coming up. Even reliable servers keep failing the QA test because of weirdness from the selected root-servers

We should either select a different group of root servers or try to find better endpoints.

Need to test a few more root-servers and maybe also use 192.175.48.1

Why not use a set of popular websites like google.com 1.1.1.1 apple.com etc. like RIPE ATLAS uses?

jimaek commented 1 year ago

Because popular sites are blocked in many countries, e.g. google is blocked in China, we need very stable endpoints that would never get banned in any country. This rules out most American companies and limits us to organizations like root-servers
