Abstract
A privatized link between an origin server and a content delivery network is provided. A privatized link can be direct connection that does not route over the internet. Another privatized link is one that rotates IP addresses. An origin server may be assigned to use a set of multiple IP addresses for communication with the content delivery network. However, at any given time, the origin server is only using a small number of IP addresses. When one of the IP addresses being used to communicate with the content delivery network comes under attack, the origin server switches to another IP address in the set in order to continue serving content to the content delivery network via an IP address that is not under attack.
