Data Coverage: Domain rankings are complete from the May–June–July 2017 crawl through the most recent release. Host rankings begin with the February–March–May 2020 crawl forward. Earlier host-level runs (2017–2019) are excluded because they contained a very large number of dangling nodes that would roughly double the database size without adding meaningful data.
