Registrar and renewals: 120 WHOIS/RDAP snapshots, 2010-04-15 to 2026-05-04 (ledger built 2026-09-27). Every renewal
Nameservers, WHOIS snapshots: 116 WHOIS/RDAP snapshots that listed nameservers, 2010-04-15 to 2026-05-04 (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.
Each mark sits at the first observation of the new state; its bracket runs back to the last observation of the old one.
