What this reading means

The site answered with a 5xx, so the edge and TLS are working and the application behind them is not.

It does NOT mean the domain or its DNS is misconfigured - the request got all the way to an application to fail there.

What produces this, in rough order of how often
  • The origin is erroring or mid-deploy.
  • An upstream in front of the origin cannot reach it.

These are the known causes, not a diagnosis of this domain. We recorded that nothing answered; we did not measure why.

Every field above is part of the same signed observation as the records below. Blank means not observed, never "none".

SIGNED-OUT VIEW Provider names, posture and counts are shown. The record values - every DNS answer, each subdomain hostname, raw TXT, IPs, cert names and WHOIS - are the product. Sign in for the full signed record, or use the API with a key.

The proof

Signed at scan time. Check the math yourself. Every line above is part of one signed observation. Re-hash it and check the Ed25519 signature in your own browser; the only network request the check makes is for the published public keys.
