How this maps to in-game ping

Real game traffic is UDP; browsers can't open raw sockets. We probe AWS S3 regional endpoints (anycast-free HTTPS) and map each SDR PoP to its nearest AWS region by great-circle distance. Expect ~5–15 ms TCP+TLS overhead vs in-game UDP, but the relative ordering of regions tracks closely.

Confidence: medium-high

Strong for relative ranking and choosing a region. Absolute numbers carry HTTPS overhead. Where AWS coverage is poor (some CN, parts of RU/ME), v0.3 will add owned WebTransport echo nodes.
