📘 FaultyPacket Internet Mail Security Observatory — Methodology, Scope & Correction Policy (v2.2 · Oct 2026)Reproducible Public DNS Evidence

Empirical Observation vs. Legal Assessment: All statistics published by the FaultyPacket Internet Mail Security Observatory (including our 338-Domain Regulated Benchmark and our rolling 10-Million-Domain Census, currently at 738,611+ domains audited) are derived from live, reproducible public DNS queries (_dmarc, SPF, MX, _mta-sts, _smtp._tls, CAA, and DNSSEC) via Cloudflare 1.1.1.1 and multi-resolver verification. Lookups that return network timeouts or SERVFAIL are classified as UNASSESSED and excluded from percentage denominators. Routing DMARC reports to a third-party or US-headquartered vendor is a technical observation from public DNS (rua= / ruf=), not an automatic legal determination under GDPR Article 44 or NIS2 Article 21; organisations should review their own transfer mechanisms (such as DPF/SCCs and processor DPAs) or route reports directly to an internal UK/EU mailbox to eliminate third-party processor overhead altogether.

Live Re-Verification & Corrections: Any domain owner who updates their DNS records can verify their live posture immediately using the FaultyPacket 20-Lookup SuperTool or request a dataset refresh at [email protected]. Raw datasets: 10M Observatory Hub · 338-Domain Study JSON · 10M Observatory Live JSON.
