Mullvad checks

A real CONNECT through the proxy + a GET to am.i.mullvad.net/json per round. The exit IP is the Fastly POP's egress IP; mullvad geolocates it and reports the city + country. km is the great-circle distance from the wireguard origin (Dallas, TX, USA) to that geoip.

Fastly POP checks

A deliberately bad-auth CONNECT per round — Fastly answers with a 4xx carrying the x-served-by debug header. From that we pull the 3-letter POP code anycast routed us to. country is resolved via the airports table (IATA → country) + wg_cities for the country name.
