## Updates from Langfuse
### 2026-08-18 12:06 UTC: investigating
Eval execution in EU region is taking longer than usual

### 2026-08-18 12:27 UTC: identified
evaluation throughput was overwhelmed by a slow tenant/model workload, with lock-expiry retries multiplying work; the concurrent worker rollout prolonged the incident.

### 2026-08-18 12:47 UTC: monitoring
our autoscaling responded slower than expected, but responded nonetheless. the backlog is draining

### 2026-08-18 13:25 UTC: resolved
Steady throughput for the last 30 minutes. Delay \< 5min.
