Common Runtime Networking Upgrade Underway

Change effective on 10 October 2024

We are adding global edge network capabilities to the Heroku Common Runtime to improve network traffic performance for all regions. This change will begin to take effect on October 10, 2024. If your application uses a custom domain, please ensure you always reference the custom domain’s DNS target with a CNAME record or equivalent and not the application’s default IP address.

An additional changelog will be posted in the coming weeks to indicate the change has been fully implemented and the change has been rolled out to all Common Runtime applications.
