As previously communicated, a major power and connectivity outage at a third-party data center in the UAE operated by a third-party vendor has impacted Cisco Duo functionality in the region. Our engineering teams have worked continuously to implement local mitigations, but the persistent instability of the regional infrastructure has required more comprehensive measures to ensure business continuity. To fully resolve these issues and restore service stability, Cisco Duo has officially initiated its Disaster Recovery (DR) process. This involves transitioning critical service dependencies and user data away from the affected UAE region to secure, high-availability data centers.
