Generally with these things (1.1.1.1), (8.8.8.8),(9.9.9.9) they multicast the IP so it resolves to about the closest one. Each "one" being its own recursive resolver.

In fact: it'd be cool to show instead. If someone from the western hemisphere and eastern both ping 1.1.1.1, they'll get response times that are smaller than the delay from NY to London.
