Observed Aug 11, 2026, 11:51 UTC (4d ago). Every field below was attested with an Ed25519 signature at scan time.
mast.br is on the survey sweep, which works its way across the whole catalog rather than returning to one name on a schedule. Putting mast.br 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 mast.br Watching a domain needs a DRM3 account. The reading above stays free and public either way.
