Public Preview: ExpressRoute Resiliency Enhancements

We are announcing couple of enhancements to ExpressRoute resiliency validation and insights: Resiliency validation is a capability designed to assess the resiliency of network connectivity for ExpressRoute-enabled workloads. This feature allows you to perform site failovers for your Virtual Network Gateway, helping to evaluate network resiliency during site outages and validate setup during migrations by testing the effectiveness of failover mechanisms. By proactively testing your network, you can ensure continuous connectivity to Azure workloads and ensure the robustness of your connections.

Resiliency insights is an assessment capability designed to measure your network's reliability for ExpressRoute workloads. At the core of this capability is the _resiliency index,_ a percentage score calculated based on factors such as route resilience, zone-redundant gateway usage, advisory recommendations, and resiliency validation tests. This index evaluates the control plane resiliency of the ExpressRoute connectivity between your Virtual Network Gateway and on-premises network(s). By analyzing and improving this index, you can enhance the robustness and reliability of your connectivity to Azure workloads through ExpressRoute.
