I want to stop Amazon Route 53 health check requests that are sent to my application.

Short description

You can configure Route 53 health checks against any public resource. If your application receives health check requests from Route 53 when you didn't configure health checks on your application, then check the following possible causes:

  • Another customer configured a health check against your application.
  • Someone configured a test health check from your account but didn't delete the health check after the test was completed.
  • Someone configured a health check against another customer's public AWS resources. However, the IP addresses of those resources were reassigned to your AWS resources. In this case, the health check applies to the reassigned IP addresses. If the previous customer based the health check on domain names, then the requests were sent because of DNS caching.
  • To balance scaling capacity, the Elastic Load Balancing service updated its public IP addresses. This means that the IP addresses are now assigned to your load balancer.

Resolution

To stop unwanted health checks requests from Route 53, complete these steps:

  1. To find the ID of the unwanted health check, review your application logs. For more information, see How can I identify and resolve unwanted health checks from Route 53?
  2. Contact AWS. If you have an AWS Support plan, then create a support case. If you don't have an AWS Support plan, then complete the Stop unwanted Amazon Route 53 health checks form. In both scenarios, include the health check ID that you found in step 1.
  3. (Optional) Block the health check IP address ranges in your firewall. To find the IP address ranges that the Route 53 health check service uses for each AWS Region, see the IP ranges JSON file. In the JSON file, search for ROUTE53_HEALTHCHECKS. For more information, see Configuring router and firewall rules for Amazon Route 53 health checks.
