Stateful engine pinned to a single zoneerror

stateful-engine-pinned-to-single-zone

A matching engine, coordination service or event store living in exactly one availability zone, with no failover and no replication, is lost with that zone. Everything that depends on it stops with it.

— all of these hold:
— the node sits inside exactly 1 availability-zone group
— any of these hold:
— the node's `failover` is "none"
— the node's `replicated` is false
— the node's `replication` is "none"
