API Reference (API Version 2012-06-01)

DisableAvailabilityZonesForLoadBalancer

Removes the specified Availability Zones from the set of Availability Zones for the specified load balancer.

There must be at least one Availability Zone registered with a load balancer at all times. After an Availability Zone is removed, all instances registered with the load balancer that are in the removed Availability Zone go into the OutOfService state. Then, the load balancer attempts to equally balance the traffic among its remaining Availability Zones.

For more information, see Add or Remove Availability Zones in the Classic Load Balancer Guide.
