Current observation
A public DMARC record was observed for 10 of 10 cohort domains; DNSSEC evidence was visible for 1 of 10.
In the latest 30 days, 40 material observations affected 3 cohort domains.
Current posture: 27 Oct 2026. 30-day window: 28 Sep 2026 to 27 Oct 2026.
These 30- and 90-day windows show material and supporting changes. Routine operational observations stay in the evidence but are not the headline.
28 Sep 2026 to 27 Oct 2026
40 material trust-posture observations and 5 supporting infrastructure observations were visible across this cohort during the selected 30-day window.
Routine observations kept separately: 2.

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.
