About This Site

Duo's Status Page shows the current health of our various deployments. New Duo Administrators with the Owner and Administrator role are automatically set up to receive email alerts when their deployment is affected. You can follow the steps in our knowledge base to determine which Deployment ID you're currently hosted if you're unsure.

The Duo Guide to Business Continuity will help you understand the two categories of Duo service outages, Duo’s failure modes and how to decide on Fail Safe vs. Fail Secure, how your applications will respond to different types of outages, and be prepared to message your users during an outage.

If you have any questions beyond the updates provided here, please contact us at support@duo.com.

Resolved - From approximately 3:36 PM to 3:56 PM EST, some customers encountered an error message displaying “Unknown Error” when attempting to edit an application’s settings in the Duo Admin Panel.

Duo routinely programmatically identifies new versions of operating systems and browsers as part of the Duo platform’s ability to enforce policy based on browser and OS version. Today a pre-release version of an operating system was identified and mistakenly set as the most current publicly available version of that operating system. Because this pre-release version has yet to be given an official version number by the vendor, an issue occurred when Duo’s policy engine attempted to determine the version number for this OS.

Duo’s Engineering team was alerted to this issue at 3:36 PM and immediately diagnosed and corrected the affected data within the platform. Updates to the platform are already underway to ensure that this issue does not happen again.
