Scheduled

Cisco is committed to providing you with a secure and reliable experience.
To ensure our DUO platform continues to meet your needs, we will be performing maintenance.

Maintenance Details :
Duo will be performing a staged rollout to rotate its server certificates to a new Root Certificate Authority (CA) bundle. This process will occur globally across all Commercial and Federal deployments.

Date and Time: April 1st, 16:00 UTC to April 10th, 00:00 UTC

Impact:
Updated Clients: Customers who have already updated their Duo software to the required versions will experience no service disruption.

Outdated Clients: Effective April 15, 2026, major browsers and operating systems will no longer trust the DigiCert G1 root certificate. Consequently, Duo protected applications and integrations running unsupported versions will experience authentication failures such as Duo Push delivery issues or API errors.
As this is a mandatory, device-level change, in order to prevent service disruptions, all systems must be updated to supported versions.

Action Required
Please ensure your environment is running the required software versions to prevent service disruption. For a full list of required versions and technical guidance, please refer to our official documentation
