  After you submit an <code>UpdateTrafficPolicyInstance</code> 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 <code>State</code> response element.

  Route 53 returns a maximum of 100 items in each response. If you have a lot of traffic policy instances, you can
  use the <code>MaxItems</code> parameter to list them in groups of up to 100.
