This reading of usad.org was taken 3d ago

usad.org is on the survey sweep, which works its way across the whole catalog rather than returning to one name on a schedule. Putting usad.org under watch moves it to the fast lane, where DomainDrift re-checks it about every 5 minutes and signs each reading, so a change becomes a dated event within minutes instead of waiting for the sweep to come round.

Watch usad.org Watching a domain needs a DRM3 account. The reading above stays free and public either way.

The proof

Signed at scan time. Check the math yourself. Every line above is part of one signed observation. Re-hash it and check the Ed25519 signature in your own browser; the only network request the check makes is for the published public keys.
