Registrar and renewals: 28 WHOIS/RDAP snapshots, 2025-01-08 to 2025-04-25 (ledger built 2026-09-27). Every renewal

Nameservers, WHOIS snapshots: 609 WHOIS/RDAP snapshots that listed nameservers, 2009-01-03 to 2026-06-12 (who.is archive). A change is placed between the nearest observations on either side, from whichever source made them; where the two sources disagree, both are shown.

Hatched = the span we hold records for. A coloured bar runs only between observations that named the same registrar or operator; nothing is assumed in between.

Certificates: 500 logged certificates (precertificate and final counted once), read 2026-10-27, reading incomplete. A bar is the issuer that issued the most certificates in those months; Internet2 renews about every 1 days (median over 63 issuance days). Public CT logging began in 2013; older certificates appear only where someone logged them later.

Each mark sits at the first observation of the new state; its bracket runs back to the last observation of the old one.
