A system and method for the management of client computing device DNS queries and subsequent resource requests within a content delivery network service provider domain are provided. The management of the DNS queries can include the selection of computing devices corresponding to various Point of Presence locations for processing DNS queries. Additionally, the management of the content requests can include the selection of computing devices corresponding to resource cache components corresponding to various Point of Presence locations for providing requested content. The selection of the computing devices can incorporate logic related to geographic criteria, testing criteria, and the like.
1. A computer-implemented method to process content requests comprising: obtaining, by a content delivery network (CDN) service provider, at a first domain name system (DNS) server, a DNS query from a client computing device, wherein the DNS query corresponds to a requested resource and comprises an
1. A computer-implemented method to process content requests comprising: obtaining, by a content delivery network (CDN) service provider, at a first domain name system (DNS) server, a DNS query from a client computing device, wherein the DNS query corresponds to a requested resource and comprises an original uniform resource locator (URL);identifying, at the first DNS server, two or more alternative DNS servers operative to receive DNS queries;responsive to the DNS query, determining performance measurement information for the two or more alternative DNS servers;selecting a second DNS server from the identified two or more alternative DNS servers, the second DNS server being selected based, at least in part, on a comparison of the performance measurement information relative to a minimum performance threshold;obtaining an alternative URL corresponding to the selected second DNS server, wherein the alternative URL is different from the original URL, wherein the original URL includes information identifying a first domain corresponding to the CDN service provider, and wherein the alternative URL includes information identifying a second domain corresponding to the CDN service provider;transmitting the alternative URL to the client computing device;obtaining, by the CDN service provider, a subsequent DNS query from the client computing device at the selected second DNS server, wherein the subsequent DNS query corresponds to the alternative URL provided by the CDN service provider. 2. The computer-implemented method as recited in claim 1 further comprising: determining whether the selected second DNS server is authoritative to the subsequent DNS query;selecting a cache component for providing content associated with the original URL if the selected second DNS server is authoritative to the second DNS query; andtransmitting information identifying the selected cache component if the selected second DNS server is determined to be authoritative. 3. The computer-implemented method as recited in claim 1, wherein the original URL corresponds to a URL provided by a content provider whereby the DNS query resolves to the first domain corresponding to the CDN service provider. 4. The computer-implemented method as recited in claim 3, wherein the content provider is different from the CDN service provider. 5. The computer-implemented method as recited in claim 1, wherein the alternative URL corresponds to a canonical name record identifier. 6. The computer-implemented method as recited in claim 1, wherein the performance measurement information corresponds to a measured latency of communications. 7. The computer-implemented method as recited in claim 1, wherein the performance measurement information corresponds to assigned categories associated with performance measurement. 8. The computer-implemented method as recited in claim 1, wherein the original URL is provided by at least one of an original content provider or the CDN service provider, the CDN service provider different from the original content provider. 9. The computer-implemented method as recited in claim 1, wherein the selection of the second DNS server is further based on an additional criterion. 10. The computer-implemented method as recited in claim 9, wherein the additional criterion includes service level information. 11. The computer-implemented method as recited in claim 9, wherein the additional criterion includes a weighted selection. 12. The computer-implemented method as recited in claim 9, wherein the additional criterion includes a cost criterion. 13. A system comprising: a first network point of presence associated with a content delivery network (CDN) service provider, wherein the first network point of presence includes a first domain name system (DNS) server that receives a DNS query from a client computing device, wherein the DNS query corresponds to requested content and comprises an original uniform resource locator (URL), and wherein the first DNS server in the first network point of presence includes a hardware component and is operative to: identify, at the first DNS server, two or more alternative DNS servers operative to receive DNS queries;responsive to the DNS query, determine performance measurement information the identified two or more alternative DNS servers;select a second DNS server from the identified two or more alternative DNS servers as a function of at least a comparison of the performance measurement information and a minimum performance threshold;obtain an alternative URL corresponding to the selected second DNS server, wherein the alternative URL is different from the original URL, wherein the original URL includes information identifying a first domain corresponding to the CDN service provider, and wherein the alternative URL includes information identifying a second domain corresponding to the CDN service provider; andtransmit the alternative URL to the client computing device; anda second network point of presence, wherein the second network point of presence includes the second DNS server, wherein the second DNS server in the second network point of presence includes a hardware component and is operative to: obtain a subsequent DNS query from the client computing device at the selected second DNS server, wherein the subsequent DNS query corresponds to the alternative URL provided by the CDN service provider. 14. The system as recited in claim 13, wherein the second network point of presence is further operative to: resolve the subsequent DNS query to identify a cache component for providing content associated with the original URL; andtransmit information identifying the identified cache component to the client computing device. 15. The system as recited in claim 13, wherein the second network point of presence is associated with the CDN service provider and determine whether the second DNS server is authoritative to the subsequent DNS query; select a cache component for providing content associated with the original URL if the second DNS server is authoritative to the second DNS query; andtransmit information identifying the selected cache component if the second DNS server is determined to be authoritative. 16. The system as recited in claim 13, wherein the original URL corresponds to a URL provided by a content provider such that the DNS query resolves to the first domain corresponding to the CDN service provider. 17. The system as recited in claim 16, wherein the content provider is different from the CDN service provider. 18. The system as recited in claim 13, wherein the alternative URL corresponds to a canonical name record identifier. 19. The system as recited in claim 13, wherein the original resource identifier is provided by at least one of an original content provider or a CDN service provider, the CDN service provider different from the original content provider. 20. The system as recited in claim 13, wherein the performance measurement information corresponds to a measured latency of communications. 21. The system as recited in claim 13, wherein the performance measurement information corresponds to assigned categories associated with performance measurement. 22. The system as recited in claim 13, wherein the selection of the second DNS server is further based on an additional criterion. 23. The system as recited in claim 22, wherein the additional criterion includes service level information. 24. The system as recited in claim 22, wherein the additional criterion includes a weighted selection. 25. The system as recited in claim 22, wherein the additional criterion includes a cost criterion.
