thepraandClaude Opus 5.5 436f7da464 CDNs found by themselves, and servers followed through time
Build / Build (push) Successful in 5m11s
Deploy / privapub.thepra.dev (push) Successful in 5m48s
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.

thepraandClaude Opus 5.5 cee85309b8 M9 (first part): the means to locate a server
- IConnectedAddresses remembers which address each host's last connection reached, set in
  SafeHttpHandlerFactory's connect callback. That is once per pooled connection, with no
  second DNS lookup, and the address is never stored.
- IGeoLocator / DbIpLocator reads the offline DB-IP Lite city and ASN databases (MaxMind
  .mmdb, via MaxMind.Db). It maps memory, swaps to new files within ten minutes, rounds
  coordinates to one decimal, never looks up a private address, and answers nothing
  when the files are missing. CdnNetworks names the CDNs whose edge addresses say nothing
  about where a server is.
- deploy/max/geo-update.sh fetches this or last month's databases, checks them and swaps
  them in atomically. The privapub-geo timer runs it monthly as www-data, and setup.sh
  installs the directory, the script, the units and a first download.

Describing servers will use these in M8.
