Monitoring - We're continuing to monitor the archival process from the previous incident. While it is making progress, it's taking longer than we hoped. We'll continue to monitor and have identified areas where we can speed up recovery. Large customers may see degraded performance in the UI but we expect this to improve as the process recovers.

Identified -
We've identified an issue with a background data-archival process in Dagster+ that may cause slower performance in some parts of the app. Runs, schedules, and sensors are not affected. A fix is being tested and we'll deploy it as soon as it's validated. We'll share further updates as progress is made.

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.
