/// Public DNS resolvers spread across regions. Anycast networks are marked as
/// such — the answering node is the one nearest to you, so "location" is the
/// operator's home region, not necessarily where the query lands. Lat/lon are
/// therefore indicative, used for the world-map view.
///
/// Every entry has been verified to answer external queries over UDP/TCP 53.
/// Africa currently has no reliable open Do53 resolver (large ISPs there
/// refuse external queries); coverage comes from the anycast networks' POPs.
