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.
