Latest update from Smartsheet

On August 11 from approximately 7:00 AM to 4:20 PM PDT, some customers experienced timeouts or failures when loading sheets and reports, as well as automation workflow failures that caused some workflows to disable due to elevated error rates. The incident was caused by a database query-routing issue related to the conditions behind recent service disruptions, where certain reads were routed to primary write servers and an edge case involving sheet synchronization amplified the resulting load. We stabilized the service by 3:20 PM PDT and confirmed full recovery by 4:20 PM PDT after scaling affected services and failing over database servers to increase capacity. We identified and deployed a permanent code fix to correct the query routing. We are also improving monitoring and safeguards to detect and mitigate similar conditions earlier.
