Solid bar: the stretch we observed that name. Dot: a single sighting. Dotted line: no record between sightings of the same name. Nothing is drawn between different names.

Registrar and renewals: 326 WHOIS/RDAP snapshots, 2007-06-30 to 2026-05-14 (ledger built 2026-09-27). Every renewal

DNS provider, registry zone files: 107 .com zone-file snapshots held, 2013-10-18 to 2026-11-02.

DNS provider, WHOIS snapshots: 551 WHOIS/RDAP snapshots that listed nameservers, 2007-09-24 to 2026-06-17 (who.is archive). Both sources feed one row per provider (hover a bar to see which); a change is placed between the nearest observations on either side, and where the two sources disagree, both are listed under What changed.

Certificates: 518 logged certificates (precertificate and final counted once), read 2026-10-27. A bar is the issuer that issued the most certificates in those months; Amazon renews about every 7 days (median over 13 issuance days). Public CT logging began in 2013; older certificates appear only where someone logged them later.
