   The server answered with an error rather than the document. The response is archived as evidence of the refusal. It is not treated as a new version and will not be diffed. This source has not yet been successfully retrieved.

   Initial archival observation. Nothing to compare against yet.

Every observation

Each row is one retrieval. Rows are never edited. A failed retrieval is kept as a record of the failure, not discarded. Rows marked with an archive badge were captured by a third party at the date shown and fetched by us later; our own retrieval time is kept separately and is never backdated.
