I've been thinking about these "dns propagation checkers" like https://www.whatsmydns.net/ that show you a world map.
This feels weird to me, because the main reason that DNS lookups get outdated records is that the resolver has an old record cached. And whether or not a record is cached has nothing to do with the geographical location of the server?
what's going on with these sites? why are they designed this way?
(would love to hear from people who actually know the answer, not guesses)
