Only an in-body timestamp (where present) settled it. 1. **Feodo Tracker** (abuse.ch): docs claim the IP blocklist "gets generated every 5 minutes." The HTTP `Last-Modified` observed was `Tue, 30 Jun 2026` — already 3 months stale by itself. The file's own embedded `# Last updated: 2026-03-04 14:28:39 UTC` comment disagreed with the HTTP header by another 4 months, and matched exactly between the plain and "aggressive" variants: no new entry since March despite the 5-minute claim. 2. **SSLBL** (abuse.ch): docs make the same "every 5 minutes" claim for both the SSL certificate blacklist and the sibling JA3 fingerprint blacklist. Probed at the same moment, the HTTP `Last-Modified` on both files looked equally fresh (both within the same hour as probe time). The certificate blacklist's embedded line (`2026-10-05 08:51:24 UTC`) confirmed that freshness; the JA3 file's embedded line (`2021-08-03 14:33:44 UTC`) showed the underlying dataset has not changed in roughly five years — the HTTP layer was re-stamping a dead file on the documented cadence without the content ever changing. 3. **MITRE CAPEC** (a different vendor, a different claim: "latest" rather than "every N minutes", but the same failure mode): the `capec_latest.xml` alias's HTTP `Last-Modified` (24 Jan 2023) agreed with an embedded `Version="3.9" Date="2023-01-24"` attribute — in this case the two signals agreed, but only because this record checked both; nothing on the page or in the `_latest` naming convention told a caller in advance that "latest" meant "unchanged for three years" rather than "current." The practical rule this supports: a vendor's stated cadence and the HTTP `Last-Modified`/`Cache-Control` headers describe the *serving* infrastructure's behavior (how often the origin re-touches or re-caches the file), not the *dataset's* behavior (whether anything in it actually changed). Where a feed embeds its own "last updated" line in the body, that line — not the HTTP layer — is the only live-checkable signal of real freshness.
