Coordinates are the real datacentre city rather than the marketing region name, because they feed the distance maths below.
Light in fibre covers about 100 km per millisecond of round trip. These are the great-circle distances to Hong Kong and the latency no network can beat — not a measurement, a limit. What you actually measure is this plus routing.

| New York | 12,956 km | 130 ms |

Within 75 km of Hong Kong — near enough that distance sets no meaningful floor between them. When several sit in one city, the fastest is the city’s real floor; a slower neighbour is usually the endpoint’s own server time.
These figures are geometry. Your own round trip to ap-east-1 depends on your connection and the route it takes — open the instrument, pick AWS, and sweep. Every region is timed from your browser against the endpoint listed above, and the result is split into the part physics demands and the part the network added.
