How do I get notifications when Amazon S3 changes its IP address?

Resolution

Create an Amazon Simple Notification Service (Amazon SNS) subscription, and then subscribe to the following SNS topic:

arn:aws:sns:us-east-1:806199016981:AmazonIpSpaceChanged

Note: For more information on this SNS topic, see Subscribe to AWS public IP address changes through Amazon SNS.

After you configure the SNS subscription, you receive a notification every time there's a change to the JSON file that contains AWS IP address ranges. To check for updated Amazon S3 IP addresses, filter the JSON file.
