# Thailand data.go.th (CKAN)

Every call to the documented action API, valid action name or not, is
intercepted by a front-end WAF before reaching CKAN and answered with a
branded, cookie-disabling `403`:

```
curl 'https://data.go.th/api/3/action/package_list?limit=2'
-> HTTP/2 403, content-type: text/html; charset=UTF-8
   cache-control: private, max-age=0, no-store, no-cache, must-revalidate
   expires: Thu, 01 Jan 1970 00:00:01 GMT
   <!DOCTYPE html>...<title>Access Denied</title>...
```

The `expires: 1970` / `no-store` cache-control pairing and the custom
"Access Denied" title (different wording from both Akamai's template seen
on `datos.gob.mx`/`data.gov.in` and Cloudflare's "Just a moment..."
template seen on `open.africa`, this lane) indicate a third, distinct WAF
product fronting this portal. As with the other blocked hosts in this
lane, the response carries no signal about whether `limit=2` or the
action name itself was ever valid — the block is unconditional, and it
applies to the bare domain root too:

```
curl 'https://data.go.th/'
curl 'https://data.go.th/api/3/action/bogus_xyz'
-> both HTTP/2 403, same WAF template and headers, but NOT
   byte-identical bodies (the page reflects the requested path back
   into itself, so the root page and the bogus-action page differ by
   a few bytes while sharing the same "Access Denied" template)
```

**How observed:** 2026-10-05T08:05Z and 08:10Z, curl 8, plain GET, no
auth.

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.
