blue-ocean.de
Observed Aug 11, 2026, 05:46 UTC (5d ago). Every field below was attested with an Ed25519 signature at scan time.
blue-ocean.de is on the survey sweep, which works its way across the whole catalog rather than returning to one name on a schedule. Putting blue-ocean.de 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 blue-ocean.de Watching a domain needs a DRM3 account. The reading above stays free and public either way.
