-- 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.
--
-- 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
-- <https://docs.aws.amazon.com/elasticloadbalancing/latest/classic/enable-disable-az.html Add or Remove Availability Zones>
-- in the /Classic Load Balancers Guide/.
