PrivaPub now finds CDNs three ways, best first: the address ranges the CDNs publish (Cloudflare, Fastly, Amazon CloudFront, Bunny, Gcore, Imperva), downloaded daily by CdnUpdater and kept in CdnRangeSet; the CDN's fingerprint in the responses it already gets from a server (EdgeHintsHandler on the federation client); and the networks that carry only a CDN. The fixed ASN list is gone; ASNs shared with plain hosting (AWS, DataPacket) no longer hide a server. A server's Geo records the CDN, its domain and how it was found, and weekly snapshots now keep the city and coordinates too. Servers through time (ServerPlaces): /instances/:host/history lists a server's weekly snapshots, a CDN-fronted server's geo names the CDN's domain and where the server was before it (before_cdn), and /api/privapub/v1/cdns and /cdns/:domain group servers by CDN with week by week who joined and who left. Owner decisions recorded in ROADMAP. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01LsXgEaXee4GCU1hwYgPJXw
