How this is measured

Tier 1. Validity window of the serving certificate. Denominator: has_web.

Passive measurement: a single DNS lookup, TLS handshake, or homepage GET per domain. Aggregate-only; no individual company is named. 95% Wilson confidence intervals. Population: domains sampled from the Common Crawl web graph, filtered to those that do email. Parked domains excluded. Snapshot: common-crawl-domain-stratified-c400-g2500-seed20260729.

Why it matters

The CA/Browser Forum is phasing certificate lifetimes down to 47 days. Any domain still on long-lived certificates has a manual renewal process that is about to break several times a year — a deadline-driven quiet failure that has not fired yet.
