What changed
- First certificate logged (Let's Encrypt) on Oct 20, 2026The earliest certificate for this name in the public Certificate Transparency logs. Logging began in 2013, so an earlier date means someone logged an older certificate later. It does not prove when HTTPS started.
Nameservers, registry zone files: 199 .best zone-file snapshots held, 2014-05-13 to 2026-10-30.
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: 2 logged certificates (precertificate and final counted once), read 2026-10-29, reading incomplete. A bar is the issuer that issued the most certificates in those months. 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.
