# DisableAvailabilityZonesForLoadBalancer
<a name="API_DisableAvailabilityZonesForLoadBalancer"></a>

Removes the specified Availability Zones from the set of Availability Zones for the specified load balancer in EC2-Classic or a default VPC.

For load balancers in a non-default VPC, use [DetachLoadBalancerFromSubnets](API_DetachLoadBalancerFromSubnets.md).

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.
