- postmortem May 18, 2026, 04:28 PM UTC
On May 7, 2026, between 20:41 and 22:26 UTC, customers in the us7: Cloud - US region experienced degraded performance. Affected customers intermittently received internal server errors when using Anaplan XL and other add-ins, which caused some refresh actions to fail. **Root cause** The issue occurred in the us7: Cloud - US region when the service that handles add-in requests became saturated and could not process inbound requests quickly enough. As demand exceeded available processing capacity, requests queued and then failed, resulting in internal server error responses for add-in users. **Recovery** Our engineering team identified the issue and took immediate action by completing a rolling restart of the impacted service, which cleared the backlog and restored normal request processing. By 22:26 UTC, the issue was fully resolved. **Corrective and preventative actions** * We are implementing improved alerting to detect increased internal server error rates earlier. * We are implementing additional monitoring for request queue behavior and saturation signals to prevent a backlog from building. * We are implementing a review and tuning of request-processing capacity to better handle spikes. * We are implementing logging improvements to speed up diagnosis and reduce recovery time for similar events. We apologize for the impact this issue has had on your operations. We are committed to the improvements outlined above to prevent similar disruptions.
