It appears to have taken only a few hours (or at most a few hours) from putting a new resolving DNS server into production to seeing outside parties specifically probing it to see if it's an open resolver.

I assume people are snooping activity on authoritative DNS servers and going from there, instead of spraying targeted queries at random IPs, but maybe they are mass scanning.
