When you update a traffic policy instance, Amazon Route 53 continues to respond to DNS queries for the root resource record set name (such as while it replaces one group of resource record sets with another. Amazon Route 53 performs the following operations:

  1. Amazon Route 53 creates a new group of resource record sets based on the specified traffic policy. This is true regardless of how significant the differences are between the existing resource record sets and the new resource record sets.

  2. When all of the new resource record sets have been created, Amazon Route 53 starts to respond to DNS queries for the root resource record set name (such as by using the new resource record sets.

  3. Amazon Route 53 deletes the old group of resource record sets that are associated with the root resource record set name.
