Once you have added all of your content delivery networks (CDNs) and configured Multi-CDN, you will need to apply your CDN provisioning to your domain. This guide walks you through the process.
A. Apply CDN Site: Click on the field to expand the dropdown menu of your previously added CDNs and choose the appropriate CDN for this configuration.
B. Record Name: In this field, enter the FQDN that you specified for your CDN. This FQDN will be the site that users will go to (virtual host).
C. TTL: Time to live (measured in seconds) determines how long a record is cached in nameservers. Visit our What is TTL resource for more information and best practices for TTLs.
To apply the CDN provision, click the green Apply button. A CDN Added successfully message will appear at the top of the page, along with a prompt to review and apply changes.
4. View CDN Records
After applying your CDN provisions, you will see the Multi-CDN configuration within each GTD region for your domain. When hovering over the pool in the DNS dashboard, you will also see all the CDN providers within the regional pool (see examples below).
Pools and sonar checks are automatically created for Multi-CDN configurations. Pools are monitored via our Internet Traffic Optimization (ITO) and Sonar applications. You can customize your pools by navigating to Managed DNS> ANAME / CNAME Record Pools.
Our Sonar Performance Monitoring tool is used to monitor the health of your CDN providers, which also allows you to identify and/or check which CDN provider has the fastest speeds. You can view this information within the ANAME/CNAME record pools and the Sonar application.
