Systems and methods for managing requesting routing functionality associated with resource requests for one or more resources associated with a content provider are provided. A content delivery network (“CDN”) service provider, on behalf of a content provider, can process domain name service (“DNS”)
Systems and methods for managing requesting routing functionality associated with resource requests for one or more resources associated with a content provider are provided. A content delivery network (“CDN”) service provider, on behalf of a content provider, can process domain name service (“DNS”) requests for resources by computing devices and resolve the DNS requests by the identification of a network address of a computing device that will provide the requested resources. Based on the processing of DNS queries initiated by a client computing device, the CDN service provider can measure CDN service provider latencies associated with the generation of DNS requests by network components associated with the client computing devices. Examples of the network components can include DNS resolvers associated with the client computing device.

1. A method comprising: obtaining, by a service provider, a first domain name service (DNS) query for content from a network component;transmitting, by the service provider, an alternative identifier responsive to the first DNS query from the network component, the alternative identifier to cause the network component to transmit a second DNS query to a component associated with the service provider;obtaining, by the service provider, the second DNS query for content from the network component responsive to the alternative identifier provided by the service provider; anddetermining, by the service provider, performance measurement information corresponding to obtaining the first and second DNS queries. 2. The method as recited in claim 1, wherein the alternative identifier corresponds to a canonical name record. 3. The method as recited in claim 1, wherein the first DNS query is associated with at least one embedded resource identifier. 4. The method as recited in claim 3, wherein the alternative identifier references a domain different from a domain associated with the at least one embedded resource identifier. 5. The method as recited in claim 1, wherein the alternative identifier includes a label representative of request routing information identifying the component associated with the service provider. 6. The method as recited in claim 1, wherein the alternative identifier further includes a label representative of additional information associated with the client computing device. 7. The method as recited in claim 1, wherein the network component corresponds to a DNS resolver component. 8. The method as recited in claim 1, wherein the first and second DNS queries are obtained at a same identifiable component of the service provider. 9. The method as recited in claim 1, wherein the first and second DNS queries are obtained at separately identifiable components of the service provider. 10. The method as recited in claim 1, wherein the performance measurement information corresponds to latency information associated with at least one of the transmittal or processing of the first and second DNS queries. 11. The method as recited in claim 1, wherein the performance measurement information corresponds to at least one of a bandwidth associated with at least one of the transmittal and processing of the first and second DNS queries, packet loss information associated with the first and second DNS queries, or throughput information associated with the first and second DNS queries. 12. A computer-implemented system comprising: a data store for storing performance monitoring information associated with network components associated with client computing device requests for content; anda computing system in communication with said data store and associated with a service provider, the computing system including at least one hardware processor operative to: obtain a first domain name service (DNS) query for content from a network component;transmit an alternative identifier responsive to the first DNS query from the network component, the alternative identifier to cause the network component to transmit a second DNS query to the service provider;obtain the second DNS query for content from the network component responsive to the alternative identifier provided by the service provider; anddetermine performance information corresponding to obtaining the first and second DNS queries. 13. The system as recited in claim 12, wherein the alternative identifier corresponds to a canonical name record. 14. The system as recited in claim 12, wherein the first DNS query is associated with at least one embedded resource identifier. 15. The system as recited in claim 14, wherein the alternative identifier references a domain corresponding to a domain associated with the at least one embedded resource identifier. 16. The system as recited in claim 12, wherein the alternative identifier further includes timestamp information. 17. The system as recited in claim 12, wherein the first and second DNS queries are obtained at a same identifiable component of the service provider. 18. The system as recited in claim 12, wherein the first and second DNS queries are obtained at separately identifiable components of the service provider. 19. The system as recited in claim 12, wherein the performance measurement information corresponds to latency information associated with at least one of the transmittal or processing of the first and second DNS queries. 20. A non-transitory computer readable storage medium storing computer executable instructions that when executed by a processor perform operations comprising: obtaining, by a service provider, a first domain name service (DNS) query for content from a network component;transmitting, by the service provider, an alternative identifier responsive to the first DNS query from the network component, the alternative identifier to cause the network component to transmit a second DNS query to a component associated with the service provide;obtaining, by the service provider, the second DNS query for content from the network component responsive to the alternative identifier provided by the service provider; and determining, by the service provider, performance measurement information corresponding to obtaining the first and second DNS queries.
