Cisco Umbrella experienced a global issue preventing customers from creating new network tunnels through the dashboard for 1.6 hours. Existing tunnels and their configurations remained fully operational throughout the incident. The service was restored and all network tunnel functionality returned to normal operation.

Cisco Umbrella experienced degraded performance with network tunnels connected to the Europe Germany Data Center, affecting some customers' network connectivity. The engineering team worked actively on mitigation efforts throughout the incident duration of 6.4 hours. The issue was fully resolved with all services returning to normal operation and network tunnel functionality restored.

Cisco Umbrella experienced a connectivity issue at the Europe Germany data center that affected customers connecting to that location for 45.9 hours. The service was mitigated by taking the affected data center out of rotation and routing customer traffic through redundant data centers. The issue was fully resolved and all services returned to normal operation.

A third-party certificate provider outage caused Cisco Secure Connect onboarding failures for new organizations and prevented newly provisioned sites from generating certificates for 2.8 hours. Existing customers and active services continued operating normally throughout the incident. The issue was resolved after Cisco's engineering team worked with the third-party vendor to restore certificate provisioning services.

Cisco Umbrella's Zero Trust Access service experienced enrollment issues affecting a limited number of customers attempting new enrollments, while existing connections remained uninterrupted.

Cisco Umbrella/Secure Connect experienced service performance issues in the Chennai and Mumbai regions, causing temporary connectivity delays and intermittent service interruptions for users accessing proxy services. The engineering team investigated and worked to stabilize the environment over a 1.3-hour period. The service performance issues were resolved and all services returned to normal operation.

Cisco Umbrella's Remote Browser Isolation (RBI) service in the Middle East (UAE) data center experienced issues causing "fail open" errors for customers in that region. The problem resulted in traffic not being properly isolated according to configured policies, with unexpected behavior when accessing the RBI service. The issue was resolved after 6.9 hours, with all services returning to normal operation.

Cisco Umbrella's Manchester data center experienced timeouts and slow connections affecting Umbrella and Secure Connect services for 7 minutes. The incident was classified as minor and the team investigated reports of degraded performance. Service was restored after identifying and resolving the underlying connectivity issues.

Cisco Umbrella experienced a partial service degradation in the Vancouver (YVR) region lasting 1.9 hours, causing customers to experience increased latency and intermittent connectivity issues. The engineering team identified the root cause and implemented mitigation steps to restore service. All services returned to normal operation after the issue was resolved.

Cisco Umbrella's sandboxing file scanning service in the Denver region experienced an issue that caused a fail-open condition for customers using Umbrella and Secure Connect services with the optional sandbox feature enabled. The impact was limited to a small subset of customers connected through the Denver EDC. The issue was resolved after 56 minutes with services returning to normal operation.
