Abstract
A content delivery network (CDN) for delivering content over the Internet is disclosed in one embodiment. The CDN includes a domain resolution service (DNS) server, caching servers and an Internet interface. The caching servers correspond to a plurality of addresses. The DNS server receives two domain resolution requests corresponding to a same domain and produces two different DNS solutions, each corresponding to a subset of caching servers. The interface receives domain resolution requests, including the two domain resolution requests, and transmits DNS solutions, including the two DNS solutions. The processing power is generally matched between the two DNS solutions.
