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