On August 28, 2025, at 11:23 UTC, our monitoring indicated a spike of authentication errors. This issue affected the following region\(s\): id1: Cloud — Indonesia. Our investigation identified an ongoing maintenance activity taking place. This activity included refreshing the infrastructure used by an authentication-related subservice. As the infrastructure was refreshed, the subservice attempted to route traffic to an unavailable node. This caused authentication requests to that node to fail. As a result, some customers may have experienced issues when logging in to the Anaplan platform. To resolve the issue, the technical team monitored the completion of the activity. Once the refresh was completed, and all nodes were available, the errors subsided. Full service was restored at 11:54 UTC. To prevent a recurrence of this issue, we're enhancing the subservice's self-healing capabilities. This will enable it to automatically detect and re-route traffic away from an unavailable node. We apologize for any impact this issue may have had on your business operations. We're continuously strengthening our systems and procedures to ensure we avoid future disruptions to your business and users.

Thank you for your patience during this situation and thank you for being an Anaplan customer.
