Nameservers, registry zone files: 144 .security zone-file snapshots held, 2016-02-04 to 2026-10-28.

Nameservers, WHOIS snapshots: 8 WHOIS/RDAP snapshots that listed nameservers, 2025-02-07 to 2026-06-19 (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.
