1. <p>Dear Amazon Web Services Customer,</p>

4. Elastic Load Balancing (ELB) endpoints. Starting today, you can use

7. availability for these apps.</p>

8. 
   
9. <p>With DNS Failover, Amazon Route 53 can help detect an outage of your
   
10. website and redirect your end users to alternate locations where your
    
11. application is operating properly. When you enable this feature, Route
    / j5 N' k( Z+ o7 ]; }1 y, `
12. 53 uses health checks—regularly making Internet requests to your
    
13. application’s endpoints from multiple locations around the world—to
    ) A, z) B& L6 o- r8 l
14. determine whether each endpoint of your application is up or down. </p>

    : j$ s) u' [$ o; e( N' g1 d$ u
16. <p>For ELB endpoints, Route 53 evaluates the health of the load balancer
    / r1 d8 W( v0 j' i1 Q
17. itself and the health of your application running on the EC2 instances

18. behind it. If any part of the stack goes down, Route 53 detects the

19. failure, routes traffic away from the load balancer, and directs traffic
    
20. to other healthy ELB endpoints. Route 53 DNS Failover also supports EC2
    
21. endpoints as well as endpoints located in your own datacenter.</p>

23. <p>Using Route 53 DNS Failover, you can run your primary application

27. on Amazon Simple Storage Service (Amazon S3), with Route 53 directing
    
28. users to this backup site in the event that your application becomes
