Shows current posture and repeated public signal through an explicitly curated, overlapping public-interest lens.
Latest observations
21 domains in this explicitly curated, overlapping lens.
Observed 10 Sep 2026.
Current observation
A public DMARC record was observed for 21 of 21 cohort domains; DNSSEC evidence was visible for 8 of 21.
In the latest 30 days, 4 material observations affected 2 cohort domains.
Current posture: 10 Sep 2026. 30-day window: 12 Aug 2026 to 10 Sep 2026.
These 30- and 90-day windows show material and supporting changes. Routine operational observations stay in the evidence but are not the headline.
12 Aug 2026 to 10 Sep 2026
4 material trust-posture observations and 1 supporting infrastructure observation were visible across this cohort during the selected 30-day window.
Routine observations kept separately: 110.
Continuous per-domain coverage cannot be established from the public manifest artefacts alone; counts use available generated event records.
13 Jun 2026 to 10 Sep 2026
46 material trust-posture observations and 7 supporting infrastructure observations were visible across this cohort during the selected 90-day window.
Routine observations kept separately: 335.
Continuous per-domain coverage cannot be established from the public manifest artefacts alone; counts use available generated event records.

Visible infrastructure links
Provider Resolution links visible MX routing and first-order SPF references to documented providers. It does not change Mail Posture.

How to read this
Inbound routing and SPF service references describe different roles. Provider names are shown only when they recur across at least three cohort domains. Smaller provider counts and privacy-sensitive distributions remain withheld. These are infrastructure associations, not supplier contracts or market share.

Evidence references for observed movement are included in the 30- and 90-day windows above. Reports and State views provide the wider panel context.
Selected domains whose continued public discoverability, authoritative communication or service accessibility has material community value beyond the organisation's own commercial interests.
Inclusion identifies why a domain is useful to observe through this curated lens. It does not imply that domains outside the cohort lack public value, and it is not a formal classification of public-interest infrastructure.
This is a descriptive cohort view. It does not rank or grade organisations.
