Transient and confirmed 5xx responses

What this finding means

A crawled request returned a server error. Amplitera records whether later bounded attempts recovered or confirmed the failure under the configured request budget.

Evidence to preserve

• Every attempt, timestamp, status, and response time
• Cache state, Ray ID, content type, size, and body fingerprint when available
• Initial and final outcome classification
• Recovered versus confirmed counts kept separate

How to repair the cause

• Investigate confirmed application or origin failures
• Use recovered evidence to diagnose intermittent infrastructure
• Avoid increasing crawler concurrency as a substitute for diagnosis
• Retest under the same request profile after the fix

How to verify the fix

Repeat bounded checks with backoff and preserve both the original failure and the later observation.

Verification reduces transient noise but cannot guarantee future uptime or prove why an external process failed without supporting logs.
