Activity Log fails to load or return errors for some users

This incident has been resolved.

**Date of Incident:** 2025-07-22 **Time of Incident \(UTC\):** 10:40 - 06:30 **Services Affected: Admin Console Activity log and User Details page** **Impact Duration:** 43 hrs ## Summary A change to our internal data model that removed an unused type definition led to multiple failures in the Reports system. ## Impact on Customers * **Events API and Reporting:** The activity log widget failed to display activities. * Admin console: User details page failed to display user details ## What Happened? A software update introduced an API change that caused a mismatch between client and server. The Audit log page in the admin console was still collecting data but was not able to render it. * **Timeline of Events \(UTC\):** * 10:40 : Detected by 1Password personnel and root cause identified * 10:42: Issue Identified * 13:38 Fix created and testing initiated * 06:30: Fix released, Service fully restored * **Root Cause Analysis:** A User State was removed from the [1Password.com](http://1Password.com) server but not the client. This was a breaking API change. ## How Was It Resolved? * **Resolution Steps:** The user state in the 1Password client was removed to get the server and client back into parity. * **Verification of Resolution:** 1Password engineering tested the changes and validated that full system functionality was restored. ## What We Are Doing to Prevent Future Incidents * **User State change process: 1Password is investigating how to catch breaking API changes by implementing additional end-to-end tests in the CI pipeline.** * Audit log architecture change: Engineering is investigating a rework of the audit log page to change how it aggregates data so that it is not reliant on an endpoint. This would mitigate future occurrences that caused this issue. ## Next Steps and Communication * No action is required from our customers at this time. * If you are still experiencing issues, please contact our support team at [support@1password.com](mailto:support@1password.com). We are committed to providing a reliable and stable service, and we are taking the necessary steps to learn from this event and prevent it from happening again. Thank you for your understanding.
