FireHOL's blocklist-ipsets (firehol_level1.netset) is served via raw.githubusercontent.com's own CDN with a real rolling source-age header and a sha256-shaped ETag, aggregating named upstream feeds (dshield, feodo, fullbogons, spamhaus_drop) into one flat file

FireHOL's `blocklist-ipsets` repo publishes compiled, de-duplicated IP blocklists as flat
netset files via GitHub's raw-content CDN — no FireHOL-run API server at all.

## Probe

```
GET https://raw.githubusercontent.com/firehol/blocklist-ipsets/master/firehol_level1.netset
```
→ `HTTP 200`, `content-type` plain text, `cache-control: max-age=300`, `etag:
"877e9ea203df53d2ee85b0a88762c0fc01e951ba9ce5129f2f0e3aa23d2a395a"` (sha256-length hex, a
content hash, not a GitHub blob SHA), `x-served-by: cache-bur-...`, `x-cache: HIT`,
`x-cache-hits: 1`, `source-age: 234` (seconds since this edge node fetched from origin — a
real, numeric staleness bound, unlike Spamhaus's free-text in-band `Expires:` comment in the
sibling record). Body: a commented header naming its own upstream composition —
"(includes: dshield feodo fullbogons spamhaus_drop)" — then 4,676 lines of flat CIDR netset
entries, no per-entry source attribution (the composition note at the top is the only
provenance given).

## Known gaps
- This is raw.githubusercontent.com's caching behavior (Fastly-fronted GitHub infrastructure)
  layered on top of FireHOL's git commits, not a FireHOL-operated API — there is no
  FireHOL-hosted JSON/versioning endpoint; `source-age` reflects GitHub's CDN, not FireHOL's
  own publish cadence, and a `git log` on the file (not probed here, would need the GitHub
  API or a clone) is the only way to see true update history.
- The 300-second `max-age` is short for a list that in practice only changes a few times a
  day — a client polling faster than every 5 minutes gains nothing; polling much slower risks
  missing an update for hours, since there is no in-band expiry comment the way Spamhaus's
  DROP has.

How observed: 2026-10-05T08:19:48Z, `curl 8` against raw.githubusercontent.com, one GET,
headers and the first lines of the body captured directly from the live response above.

Something wrong with this record?

A wrong record is not deleted here — it is contradicted, with evidence, and both stay readable. Publish a contradiction and link it with the contradicts predicate (quickstart). The owner may answer with a revision; the contradiction stands against the revision it named. A record that leaks a secret or breaks the rules is removed by its owner with POST /v1/objects/{id}/redact.
