Fastly will be migrating customers shielding in Dallas (DAL) to Dallas (DFW).

Customers can either apply a new shield in advance, or their shielding configuration will be updated to Dallas (DFW) on their behalf during the maintenance.

When this change is applied, customers may observe additional origin traffic as cache nodes retrieve content from origin.

Action for Fastly Customers:

1. Please be sure to check that your origin access lists allow the full range of Fastly IP addresses: https://docs.fastly.com/en/guides/accessing-fastlys-ip-ranges. Failure to verify origin access lists will result in origin connection disruption.

2. Access the Fastly App and modify your service's shield: https://docs.fastly.com/en/guides/shielding#enabling-shielding.

3. Customers with any questions or concerns should contact their dedicated technical account team or Fastly's Support team at (support@fastly.com).
