HTTP_STATUS_SITE_FROZEN
The AllStat source identifies Pantheon for this code, where it is associated with a site state controlled by the hosting platform. Because 530 is vendor-defined, other services can use it differently.
Identify the emitting platform from headers or the response body, then check the site/account state in that platform. Do not apply Cloudflare 530 guidance to a Pantheon-generated response or the reverse.

Operational meaning of HTTP 530 for HTTP_STATUS_SITE_FROZEN
HTTP 530 (this result) is a server-error response. AllStat records its meaning as “530 Site is frozen”. Interpret it with the request method, selected representation, response headers, and the specification or product that defines the code; the number alone does not prove that application work completed.
Client and server handling
- Correlate this result with origin, gateway, load-balancer, and dependency logs to locate which hop generated it.
- record request and trace identifiers, upstream timing, retry count, and the health of the selected backend.
- use bounded retries with backoff only for idempotent work and only when the service policy permits them.
For telemetry, record HTTP 530, method, authority, route template rather than secrets, response headers relevant to caching or retry, latency, upstream identity, and whether the response originated at the application or an intermediary.
