Some embodiments provide systems and methods for determining a server of a distributed hosting system to optimally distribute content to an end user. The method includes identifying an IP address of the end user. Based on the IP address, a set of servers send packets to the end user to derive performance metrics. The performance metrics are used to determine a server from the set of servers that optimally distributes content to the end user. The method modifies a configuration for resolving end user requests such that the optimal server is identified to the end user when the end user requests content from the hosting system. Some embodiments determine the optimal server by providing downloadable content that is embedded with a monitoring tool. The monitoring tool causes the end user to derive performance metrics for the hosting system when downloading a particular object from a set of servers.

1. A method for optimizing content delivery performance from a particular site of a content delivery network (CDN) comprising a plurality of servers, the method comprising: with at least one server of the particular site comprising a processor: receiving a request for content from a particular end user;selecting according to a CDN configuration, a first network route from a plurality of network routes that provides a best performing path from the particular site to the particular end user;providing said content from the particular site to the particular end user over the first network route, said content comprising a monitoring tool which when processed by the particular end user causes the particular end user to download a common downloadable object from the particular site over each of the plurality of network routes;receiving from the particular end user, metrics measuring performance in delivering the common downloadable object over each of the plurality of network routes to the particular end user; andmodifying the CDN configuration by specifying a second different network route of the plurality of network routes instead of the first network route as the best performing path to the end user when said metrics indicate that the second route provides better performance than the first route. 2. The method of claim 1 further comprising providing the common downloadable object from the particular site to the particular end user over at least the first and second network routes of the plurality of network routes. 3. The method of claim 2, wherein receiving the metrics comprises receiving a first metric providing a performance measurement derived from passing the common downloadable object from the particular CDN site to the particular end user over the first network route and a second metric providing a different performance measurement derived from passing the common downloadable object from the particular CDN site to the particular end user over the second network route. 4. The method of claim 1 further comprising receiving a second request for second content from the particular end user and providing the second content from the particular site to the particular end user over the second network route that the CDN configuration identifies as the best performing path to the particular end user after said modifying. 5. The method of claim 1, wherein the monitoring tool further causes the particular end user to download the common downloadable object from at least a second different site of the CDN that is geographically separated from the particular site. 6. The method of claim 5 further comprising receiving from the particular end user, metrics measuring performance in delivering the common downloadable object to the particular end user from the particular site and the second different site. 7. The method of claim 6, wherein modifying the CDN configuration further comprises specifying the second site instead of the particular site when the metrics from the particular end user identify the second site as providing better performance than the particular site. 8. The method of claim 1, wherein the content is skeleton content with links to a set of embedded objects. 9. The method of claim 1, wherein the monitoring tool comprises an executable script. 10. The method of claim 1 further comprising configuring the monitoring tool with addressing for each of the plurality of network routes and embedding the monitoring tool within the content. 11. A method for optimizing content delivery performance from a hosting site of a hosting system to a plurality of end user clusters, wherein each end user cluster comprises at least one of end users operating in a common geographic region, end users assigned Internet Protocol (IP) addresses of a common IP address block, and end users accessing the hosting site from a common network intersection point, the method comprising: with at least one machine of the hosting site comprising a processor: providing a network route configuration specifying, for each end user cluster of the plurality of end user clusters, a network route from a plurality of available network routes providing an optimal path from the hosting site to the end user cluster;receiving a request for content from an end user of a particular end user cluster of the plurality of end user clusters;responding to the request by (i) identifying a first route from a plurality of network routes that is specified in the network route configuration as the optimal path to the end user cluster and (ii) passing said content with an embedded monitoring tool through the first network route, said monitoring tool comprising instructions which when executed by the particular end user as part of processing the content cause the particular end user to download a common downloadable object through each of the plurality of network routes;receiving from the particular end user, metrics measuring performance for delivering the common downloadable object from the hosting site through each of the plurality of network routes to the particular end user; andmodifying the network route configuration by specifying a second different network route of the plurality of network routes instead of the first network route as the optimal path to the particular end user cluster based on said metrics from the particular end user. 12. The method of claim 11 further comprising serving the common downloadable object through each of the plurality of network routes to the particular end user. 13. The method of claim 11, wherein the monitoring tool further comprises instructions which when executed by the particular end user as part of processing the content cause the particular end user to trace each of the plurality of network routes back to the hosting site. 14. The method of claim 11, wherein each network route of the plurality of network routes comprises a plurality of network hops connecting the particular end user with the hosting site, and wherein the plurality of network hops for the first network route differ from the plurality of network hops for the second network route by at least one hop. 15. The method of claim 14, wherein said metrics provide a time measurement for sending a packet between the particular end user and one network hop of the plurality of network hops for each network route of the plurality of network routes. 16. A content delivery network (CDN) hosting and delivering content, the CDN comprising: a database server comprising a non-transitory computer-readable medium storing a configuration specifying a first route of a plurality of routes as a best performing path through which to serve content from a CDN site to any end user of a particular end user cluster;a content distribution server in said CDN site responding to a request for content from an end user of the particular end user cluster by (i) embedding the content with a monitoring tool comprising instructions which when executed by the end user cause the end user to download a common downloadable object through each of the plurality of routes and (ii) serving the content embedded with the monitoring tool to the end user through the first route that is selected from the plurality of routes based on said configuration; anda monitoring server (i) receiving performance metrics from the end user identifying content delivery performance from the CDN site to the end user through each route of the plurality of routes and (ii) modifying the configuration by specifying a second route of the plurality of routes instead of the first route as the best performing path from the CDN site to any end user of the particular end user cluster when the performance metrics from the end user identify that the second route results in better content delivery performance from the CDN site to the end user than the first route. 17. The CDN of claim 16 further comprising a second content distribution server in said CDN site responding to a second request for content from a different end user of the particular end user cluster by serving the second content to the different end user through the second route identified by the configuration after said modifying as the best performing path to the particular end user cluster. 18.
