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.

To manually sign up for alerts, click the "Subscribe to Updates" button in the upper-right hand side of this page. SMS notifications are triggered when we create or resolve an incident. Email notifications are triggered when we create, update, and resolve an incident. You can find more information about how alerts work in our knowledge base.

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.

Postmortem - Read details
Sep 27, 02:20 EDT
Resolved - We have finished monitoring the applied fix, and all the Device Health applications for Chromium-based browsers on the latest version of macOS and Windows are now operational. We will provide an RCA as soon as it is available.
Sep 27, 02:09 EDT
Monitoring - We have finished rolling out the fix to all customers. We are currently monitoring the performance of the solution.
Sep 26, 01:00 EDT
Identified - We have identified the communication issue between the Duo prompt and the Device Health Application for Chromium-based browsers on macOS and Windows, which will make it so that users running the latest version of the browsers will be prompted to install the Device Health Application even when it is already installed, and will not allow authentication, if your Policy settings require it.

The issue is caused by a new Chrome certificate store and acceptable Certificate Authorities.

Google is rolling out this specific change to their certificate store as a rolling release, so not everyone on the latest version of Chrome has this change yet.

Other browsers, such as Firefox and Safari, are currently unaffected. All other services are fully operational and customers who do not use the Device Health Application are unaffected.

We are currently working on rolling out a fix for all customers.

Completed - The scheduled maintenance has been completed.
Sep 17, 03:57 EDT
In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.
Sep 17, 03:30 EDT
Scheduled - We are scheduling a critical maintenance on 17 September 2022 on the DUO1 Deployment, from 07:30 UTC to 08:00 UTC.

We've selected this time window based on our analysis of non-peak authentication times, so as to limit the effect on DUO1 customers.

During this time, we expect a few intermittent failures in authentication when users attempt to log in. Users should wait a few minutes before trying again.

We will mark the scheduled maintenance as resolved upon completion of the work.
