Summary — Our investigation of the incident is complete, and we would like to provide details about the service disruption that affected access to our platform on June 11, 2026, between approximately 3:27 PM and 4:05 PM \(CEST\). Customers on the European and Americas systems experienced a temporary loss of access. Our teams successfully identified the cause and restored full service functionality.

What Happened — A recent backend update introduced a change to database query handling that consumed more system resources in production than anticipated from testing. As a result, backend services became temporarily unavailable, preventing users from accessing the platform. Our team identified the cause, reverted the change, and restored normal operations.

Impact — Between approximately 3:27 PM and 4:05 PM \(CEST\) on June 11, 2026, users on the European and Americas systems were temporarily unable to access App/Intranet. The European system was affected from approximately 3:27 PM to 3:54 PM, and the Americas system from approximately 3:27 PM to 4:05 PM \(CEST\).

Future Improvements — We have confirmed that recently added data fields are properly indexed and optimized for full production scale, and we have refined our recent database queries for efficiency. We have also enabled automated validation of our database indexing so that potential issues are caught proactively. In addition, we continue to enhance our internal monitoring and refine our rollback procedures so we can detect and resolve similar issues even faster in the future.

Thank you for your patience and understanding while we work to improve our services and prevent future incidents.
