- API Timeout Investigation
- [Q] Why are requests timing out after deployment?
- [C? @db-pool] The timeout is caused by database connection pool exhaustion.
- [G @acq-fail] Error logs show repeated connection acquisition failures.
- [@prod-logs ~> @acq-fail] Production logs from 02:00–03:00.
- [O] Increased upstream latency may be the actual cause rather than a downstream symptom.
- [G] The same logs also show increased upstream latency.
- [R; @temporal-rebuttal] Upstream latency begins after connection failures, not before.
- [? ~> @temporal-rebuttal] Need timestamp ordering across services.
- [D] Distinguish root cause from downstream symptom.Compiled structure
