Worth knowing
Most of these addresses are anycast, so the city beside a resolver is where that operator's node sits relative to us — not a guarantee of which node answered. Treat the spread across regions as the signal, not any single row.
Queries go straight to each resolver's own IP over UDP port 53, so nothing in between is caching the answer. A record that has not changed yet has genuinely not propagated.
