Liquid Web’s Content Delivery Network is a fantastic way to get elements of your site to your global customers in a timely manner. As part of the set up process, you may need to add a Canonical Name (CNAME) record to your domain’s DNS.

If we manage your nameservers, or if your DNS is hosted on our nameservers, our Heroic Support technicians will take care of this step. If not, as part of the CDN set up process you will need to add the following line to your domain’s zone file:

cdn.domain.com. 300 IN CNAME sourcecdn.edgesuite.net.

Substitute your domain for “domain.com” in the above example. Also make sure you follow any other necessary steps your DNS provider might require for updates to your zone file.

Why Do I Need a CNAME For My CDN?

The CNAME entry points any references to cdn.domain.com in your site code to the Content Delivery Network. For most content management system CDN plugins, simply putting the cdn.domain.com in the plugin configuration will allow site assets to be downloaded from locations across the globe.
