High availability for cloud-based services like AI agents is achieved through redundant and distributed systems. The underlying platform, Microsoft Azure, hosts Copilot Studio on a globally distributed infrastructure. This architecture ensures that if one component or data center fails, traffic is automatically rerouted to healthy instances, minimizing downtime and maintaining service continuity. This approach eliminates single points of failure, which is fundamental to providing a reliable and always-on user experience.

A single server deployment creates a single point of failure, which is the antithesis of high availability.

Manual backups only are a disaster recovery strategy for restoring data after a failure, not a high availability strategy for preventing downtime.

Static responses relate to the agent's conversational content, not the uptime or availability of its underlying infrastructure.

To achieve these SLA levels, Power Platform services are hosted in datacenters around the world and use Azure's high-availability features, such as fault domains and update domains."
