We are excited to announce the release of DNS Failover for Route 53, Amazon’s Domain Name System (DNS) web service. With DNS Failover, Amazon Route 53 can help detect an outage of your website and redirect your end users to alternate locations where your application is operating properly. When you enable this feature, Route 53 health-checking agents will monitor each location (or "endpoint") of your application to determine its availability. In the event an endpoint fails, Route 53 will route traffic away from the failed endpoint and to other, healthy endpoints. This helps add redundancy to your applications and maintain high availability for your end users.
You can take advantage of Amazon Route 53’s traffic management capabilities to improve the availability of your applications. For example, if you host your website on Amazon EC2, you can now leverage a simple backup site hosted on Amazon S3. You can also run your primary application simultaneously in multiple AWS regions around the world, with Route 53 automatically removing from service any region where your application is unavailable.
Getting started is easy, and there are no upfront costs. See the Route 53 product page for full details and pricing.
