Final Reminder of Change to IP Addresses for ASA Requests on August 22

This is a final reminder that as of August 22, 2023, we will no longer guarantee that ASA requests will be sent from our published set of static IP addresses. This change follows our release of HMAC headers in ASA requests in May, and we strongly recommend that customers implement ASA request verification with HMAC as soon as possible.

Please refer to this changelog post from May for more on the change and this page in our documentation for more on setting up your HMAC implementation.
