-- You start a zonal shift to temporarily move load balancer traffic away
-- from an Availability Zone in a AWS Region, to help your application
-- recover immediately, for example, from a developer\'s bad code
-- deployment or from an AWS infrastructure failure in a single
-- Availability Zone. You can start a zonal shift in Route 53 ARC only for
-- managed resources in your account in an AWS Region. Resources are
-- automatically registered with Route 53 ARC by AWS services.
--
-- At this time, you can only start a zonal shift for Network Load
-- Balancers and Application Load Balancers with cross-zone load balancing
-- turned off.
--
-- When you start a zonal shift, traffic for the resource is no longer
-- routed to the Availability Zone. The zonal shift is created immediately
-- in Route 53 ARC. However, it can take a short time, typically up to a
-- few minutes, for existing, in-progress connections in the Availability
-- Zone to complete.
--
-- For more information, see
-- <https://docs.aws.amazon.com/r53recovery/latest/dg/arc-zonal-shift.html Zonal shift>
