-- Gets information about a specified traffic policy instance.

-- After you submit a @CreateTrafficPolicyInstance@ or an
-- @UpdateTrafficPolicyInstance@ request, there\'s a brief delay while
-- Amazon Route 53 creates the resource record sets that are specified in
-- the traffic policy definition. For more information, see the @State@
-- response element.
--
-- In the Route 53 console, traffic policy instances are known as policy
-- records.
