-Standard resiliency in ExpressRoute is a single circuit with two connections configured at a single site. Built-in redundancy (Active-Active) is configured to facilitate failover across the two connections of the circuit. Microsoft guarantees an availability [service level agreements (SLA)](https://www.microsoft.com/licensing/docs/view/Service-Level-Agreements-SLA-for-Online-Services?lang=1) for Microsoft Enterprise Edge (MSEE) to the gateway for this configuration. Today, ExpressRoute offers two connections at a single peering location. If a failure happens at this site, users might experience loss of connectivity to their Azure workloads. This configuration is also known as *single-homed* as it represents users with an ExpressRoute circuit configured with only one peering location. This configuration is considered the *least* resilient and **not recommended** for business or mission-critical workloads because it doesn't provide site resiliency.
