- identified Aug 14, 2026, 09:24 PM UTC
We have identified the cause of the degraded performance impacting Orchestrator in US region and are working on mitigation. Impact: Users may experience delayed loads and views on Orchestrator Robot logs. Additional updates will be provided as we move toward resolution.
- resolved Aug 14, 2026, 11:22 PM UTC
The issue has been resolved and Orchestrator Robot logs performance has returned to expected levels after degraded performance impacted Robot logs to load in US region. Impact: No ongoing user impact.

## Customer impact Between August 14, 2026 at 8:54 pm UTC and August 15, 2026 at 2:09 AM UTC, a subset of customers in the US region experienced significant slowness in the Orchestrator Jobs and Logs pages, and robot logs appeared later than expected in the logs view. Performance had substantially recovered by 11:22 PM UTC on August 14, with full recovery confirmed with affected customers at 2:09 AM UTC on August 15. Automation execution was not affected, jobs continued to be scheduled and to run normally throughout. No log data was lost. Logs continued to be recorded and became visible once the system caught up. Requests did not fail, so no errors were surfaced, pages were slow to load and recent activity appeared missing or delayed. No other region was impacted. ## Root cause Orchestrator stores and retrieves robot logs using a dedicated search and storage system. Routine maintenance on that system causes data to be redistributed internally across the cluster. Our analysis indicates that a redistribution larger than anticipated consumed capacity that would otherwise have served customer requests, slowing both the retrieval of existing logs and the processing of new ones. This accounts for the majority, but not the entirety, of the slowdown observed, and analysis of the remaining contributing factor is continuing. Capacity returned to normal without intervention, at which point log visibility and page performance recovered. ## Detection The issue was surfaced through customer reports of slow Jobs and Logs pages in the US region. ## Response We posted a status update confirming that we were investigating degraded Orchestrator performance in the US region. Our engineering team scoped the impact to the US region and narrowed the slowdown to the log storage and search layer. The degradation stemmed from capacity contention that eased as the redistribution completed, and responders monitored the system through recovery. Page performance and log visibility returned to expected levels over the course of the evening, and recovery was subsequently confirmed with affected customers at 2:09 AM UTC on August 15. ## Follow up 1. We are adding monitoring and alerting on the response times customers experience and on the delay between a robot log being generated and becoming visible, so that degradation of this kind is detected proactively. 2. We are documenting an operational procedure that gives our on-call engineers defined steps to reduce customer impact during this class of degradation. 3. We are changing how routine maintenance on the log storage system is scheduled and paced in the US region so that it does not affect customer-facing performance. 4. We are increasing spare capacity in the log storage system so that internal data movement has room to complete without competing with customer requests.
