Is Orion configured for high availability under the Nephele service?

Nephele uses a single multi-tenant Orion server instance per cluster of ISV accounts. Based on our experience to date with the Acropolis hosting service, we anticipate the uptime to be in excess of 99.84% without the need for a failover configuration.

That being said, Orion is capable of being configured for automatic failover; this an option under the dedicated hosting service tier as part of an Acropolis license.
