• resolving a request for content associated with the private-labeled CDN namespace to identify one of the content servers in the private-labeled content delivery network and attempting to serve the content from the one of the identified content server in the private-labeled content delivery network;
• and
• if load on the private-labeled content delivery network exceeds a given threshold, resolving an additional request for content associated with the private-labeled CDN namespace to identify one of the content servers external to the private-labeled content delivery network and attempting to serve the content from the one of the identified content server external to the private-labeled content delivery network;
• wherein the requests for content associated with the private-labeled CDN namespace are processed by the DNS request handling mechanism associated with the CDN namespace;
• wherein the given benefit is a reduction in a rate paid by the NSP for off-net content delivery;
