# DemoHighLatency — 2026-09-07

- **Service**: demo-app
- **Severity**: warning
- **Status**: firing
- **Summary**: demo-app latency degradation

## Root cause
The demo-app latency degradation is caused by an active chaos experiment injecting latency (latency_mode=1), which started at 23:53:25Z and correlates with the elevated 5m error ratio of 0.368. Although logs show "chaos cleared" at 23:54:15Z, the latency_mode flag remains at 1, indicating the chaos injection is still active.

## Evidence
- up: 1
- error_ratio_5m: 0.3680555555555556
- heap_alloc_bytes: 204320
- heap_trend: n/a
- latency_mode: 1

## Suggested first action
Disable the chaos latency injection by setting demo_latency_mode=0 to stop the artificial latency and allow the service to recover.
