Source-backed troubleshooting guides for HTTP and cloud errors. Built for engineering teams that need fast, accurate answers.
Complete index of provider error codes and deep troubleshooting pages.
Browse by failure class: auth, quota, validation, availability, and more.
Decision guides for commonly confused errors like 401 vs 403.
Cross-error incident runbooks for timeout, auth, CORS, and throttling failures.
Our HTTP reference library maps each status code to standards-based semantics and real remediation paths for API and web teams. Every page clarifies when a response is expected, when it signals a defect, and how to verify the fix in production traffic.
Our AWS error library covers high-impact exceptions across S3, IAM, EC2, Lambda, and DynamoDB with service-specific diagnostics. Each entry is written for incident workflows using RequestId and HostId evidence, policy scope checks, and quota or regional constraint analysis.
Our Azure reference focuses on ARM deployment failures, Entra ID authentication and authorization errors, and storage/runtime service exceptions. Each guide maps provider messages to actionable checks across tenant, subscription, resource group, and policy layers used in real operations.
Our GCP library tracks canonical API and gRPC-style error patterns across IAM, quotas, networking, and resource lifecycle operations. Each page explains how to isolate the failing principal, project, or service boundary and confirm remediation with repeatable verification steps.
Error Reference is an editorially reviewed knowledge base covering HTTP, AWS, Azure, and GCP errors. Each page focuses on practical root-cause analysis, remediation steps, and implementation-ready code examples. References link back to official documentation so teams can validate details before production rollout.
