## Service Alerts

### Payment Latency

For `HighLatency` alerts on `payment-service`, treat p95 latency as the primary symptom.

Diagnosis steps:

1. Confirm whether p95 latency is isolated to payment-service or shared across upstream callers.
2. Compare payment-service latency with downstream dependency latency for gateway, risk, and order services.
3. Check connection pool wait time, retry spikes, and timeout rates.
4. If downstream dependency latency increased first, classify payment-service as affected rather than root cause.

The expected evidence terms are p95 latency, payment-service, and downstream dependency.
