1.71% of domains in Thailand (95% CI 0.67–4.31%), measured across 234 domains on 2026-08-15.
Measured every Saturday since 2026-08-01 — 4 observations to date. Last measured 2026-08-15.
How this is measured
Tier 1. Subdomain enumeration (CT + DNS) plus dangling-target analysis, via one cached DomainAPI call per domain. Denominator: any, on a capped subset (heavy).
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 archetypal quiet failure — a CNAME left pointing at a cancelled SaaS account. Nothing is broken, nothing alerts, and anyone who registers that account now serves content on your domain, with your name and often your cookies.
