lhc.org.uk is on the survey sweep, which works its way across the whole catalog rather than returning to one name on a schedule. Putting lhc.org.uk 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 lhc.org.uk Watching a domain needs a DRM3 account. The reading above stays free and public either way.

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.
