## Delays in Asynchronous Actions and Workflows ‌ **Issue Summary** On May 28, 2026, we experienced an incident that caused delays in asynchronous actions and automated workflows. **Timeline \(UTC\)** * **11:29** – The issue began, causing delays in newly scheduled automated workflows. * **15:51** – Our engineering team identified the root cause of the scheduling interruption. * **16:42** – A fix was deployed, restoring normal operations to the background processing framework. * **18:45** – The resulting backlog of delayed tasks was completely cleared and normal service was confirmed. **Root Cause** A routine system update included a software dependency upgrade that unexpectedly conflicted with our background processing framework. This conflict prevented scheduled background jobs from moving into the active processing queue. As a result, automated workflows and other asynchronous actions were delayed, though no underlying data was lost or corrupted during this time. **Resolution** Upon investigating the anomaly in the scheduling queue, our engineering team determined that the recent dependency upgrade was responsible. We immediately reverted the update, which restored the flow of scheduled tasks. To resolve the issue as swiftly as possible, we temporarily scaled up our infrastructure's processing capacity to rapidly clear the backlog of delayed actions. **Preventative Measures** To prevent this type of issue from occurring in the future, we are planning on implementing the following improvements: * **Enhanced Alerting:** We are deploying strict, automated alerts specifically designed to detect anomalies in scheduled task queues, drastically reducing our time to detection. * **Upgraded Telemetry:** We are adding granular, time-series visualizations to our monitoring systems to better track the exact states of background jobs \(scheduled, enqueued, and processed\) in real time. We sincerely apologize for any disruption this may have caused to your operations. The issue was fully mitigated, and all backlogged tasks have been successfully processed.

Some users experienced an issue where app.circle.so was unavailable. This was caused by the Redis cluster reaching 100% CPU due to a large volume of workflow jobs being re-enqueued. We identified the root cause, scaled down the background deployment pods to relieve the load, and restored service within approximately 3 minutes. We are continuing to investigate and address the underlying issue.
