This reading of bfu.bg was taken 2d ago

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