How to interpret this dataset

The default view includes verified crawler requests to Scrubnet feeds. Verification uses published provider IP ranges or forward-confirmed reverse DNS where available. “Content age” is the time between a resource’s recorded modification date and the request; unknown or future dates are excluded from age statistics and reported through coverage counters.

Request counts show access to Scrubnet, not indexing, ranking, training, retrieval or citation. Format totals are descriptive. Coverage denominators use the latest daily inventory snapshot and are unavailable when a path filter is active.
