Today, we are announcing the availability of Route 53 Resolver Query Logging in the Canada West (Calgary) Region. Route 53 Resolver Query Logging enables you to log DNS queries that originate in your Amazon Virtual Private Clouds (Amazon VPCs). With query logging enabled, you can see which domain names have been queried, the AWS resources from which the queries originated – including source IP and instance ID – and the responses that were received.
