manifest.json lists the size and SHA-256 hash of every original file. SHA256SUMS is the checksum file of the GitHub Release data-2026-10-14-research-tenth, created when this was the current data, and every file listed here matches it; these checksums do not change when the site builder changes. datacenter-atlas-2026-10-14-research-tenth.zip and atlas.json link to that release's frozen assets; the other derived formats are served here, byte for byte as the release lists them. This page itself is not in SHA256SUMS or the zip.
