Important

On May 15, 2019, we're adding the following IP address range for Route 53 health checkers to support the continued growth of Route 53 health checking:

15.177.0.0/18

If your firewalls or security groups restrict incoming traffic based on source IP addresses, confirm that your configuration allows traffic from the new IP address range.

For more information about IP addresses for health checks, see Configuring Router and Firewall Rules for Amazon Route 53 Health Checks.
