Snapshots (1)

One entry per time this address is known at: Wayback snapshots we captured, our live fetches, and times the catalogue declares (as_of) without a capture. Each capture is our stored copy, with its provenance.

Checks (2)

Every time this address was looked at and what came back. A check that found no content is a record of the attempt, not a snapshot.
