A cache miss that times out against FrankerFaceZ or IVR was returned as 502, and the next request during backoff as 503. Serve any copy still held, keep provider 404s as negative cache, and log upstream failures apart from Worker faults. Add /health for a check that does not call a provider.

There was a problem hiding this comment.
deployment notes way too large and no proper format. please include also steps regarding access safety for cloudflare one zto if needed regarding health checkpoint from clientside. please also pay more attention to using clean code.

One helper writes Worker log lines. Provider failure reasons are a const, and the 7TV test id prefix is named. Co-authored-by: Fabian Zimber <[email protected]>
Name upstream reasons, log Cloudflare platform failures through one error type, and let the cache path read as early returns. Co-authored-by: Fabian Zimber <[email protected]>

Rewrote the description into Summary, Changes, Testing, Deployment notes, and Access / Zero Trust. No Access application is defined in this repo; the Access section says what to add if one is attached later. The degrade path is named functions and constants, without the narrative comments. |
