1. A method of directing access to an Internet resource to a preferred infrastructure that hosts a copy of the Internet resource, the method including:
receiving a DNS query to resolve a hostname; identifying a hostname alias mapped to the hostname; selecting a program code associated with the hostname alias and invoking the program code, the program code accessing infrastructure status data for two or more infrastructures that operate within their own distinct content delivery networks and selecting an infrastructure of the two or more infrastructures for use in accessing resources associated with the hostname alias; receiving from the selected program code an identification of the selected infrastructure, the identification based, at least in part, on the infrastructure status data; and responding to the DNS query with a DNS response that directs DNS resolution of the hostname towards the selected infrastructure. |
