Error Categories groups HTTP and cloud failures by operational class so engineers can narrow root-cause domains quickly. Each category maps common failure signatures to provider-specific codes across AWS, Azure, GCP, and HTTP. Use this taxonomy-first view to triage incidents before moving into detailed per-code diagnostics.
Identity proof failures caused by missing, invalid, or expired credentials.
Permission and policy denials after identity has been authenticated.
Traffic throttling and quota-capacity exhaustion under load.
Missing resources, wrong scope, lifecycle drift, and state mismatches.
Transient outages, upstream faults, and service instability events.
Schema, contract, and parameter constraint validation failures.
Version conflicts, concurrent writes, and precondition failures.
Network path, timeout budget, and connection management issues.
Cross-cutting failures that span multiple operational categories.
