Starting today, Amazon Route 53 supports geoproximity routing as an additional routing policy for DNS records in public and private hosted zones. Geoproximity routing improves application responsiveness for your end users and helps organizations apply data residency preferences by routing traffic to the geographically nearest resource. With this release, you can add geoproximity routing to your DNS records via the Route 53 Console, API, SDK, and CLI.
