Network path, timeout budget, and connection management issues.
Last reviewed: February 13, 2026|3 mapped errors
Network-timeout errors emerge when transport path issues or mismatched timeout budgets prevent requests from completing in expected windows.
Provider-specific error pages mapped to this category (3 total). Showing 1-3.
GCP DEADLINE_EXCEEDED means the client deadline expired before receiving a response, even if server-side work might have completed.
HTTP 408 Request Timeout means the server did not receive a complete request message within its timeout window.
HTTP 421 Misdirected Request means the request reached a server that is not able to produce a response for the target authority.
Because upstream gateways or dependencies can still expire first. Timeout budgets must be aligned across every hop, not only client-side.
Deadline inversion happens when an upstream component has a longer timeout than its caller, allowing work to continue after caller timeout and wasting capacity.
Use hop-level telemetry: DNS/TLS/connection metrics identify transport failures, while application spans show server processing and dependency delay.
