Degraded sensor and schedule evaluations
Resolved - Between 1:00pm and 1:24pm PT (20:00–20:24 UTC), Dagster+ had trouble communicating with agents. During this window, some sensor and schedule evaluations failed or timed out, and some runs may have started late. Service has recovered. Sensors and schedules are evaluating normally, and failed ticks will resume on their next evaluation. We're monitoring and investigating the root cause.
