colos.json (Cloudflare colo dataset)

Public dataset, sourced from Cloudflare

The list of Cloudflare points-of-presence we surface in the colo info panel is sourced from speed.cloudflare.com/locations — a public endpoint Cloudflare maintains for their own speed test. We snapshot the response into our repository at build time so the UI can render colo names without making a runtime call to a third party.

The snapshot is taken by scripts/snapshot-colos.ts and written to src/lib/speedtest/colos.json. We treat the dataset as Cloudflare’s content; this entry is here to acknowledge the source rather than to assert a license over a public list of airport codes and city names.

Refresh the snapshot with npm run snapshot-colos when Cloudflare adds new POPs.

MIT License — technique reference

Inspired our anycast-aware colo discovery thinking; we don’t use their code, but the technique informed our design.
