Abstract: A system, methods, and interfaces for managing request routing functionality associated with resource requests for one or more resources associated with a content provider. The request routing functionality can correspond to the processing of domain name service (“DNS”) requests for resources by computing devices and the resolution of the DNS requests by the identification of a network address of a computing device that will provide the requested resources. Unlike traditional CDN service provider implementation, the processing of resource requests by the service provider is separate from the delivery of the content by the content provider (or on behalf of the content provider).

Abstract: 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, performance threshold criteria, testing criteria, and the like.

Abstract: 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.

Abstract: Generally described, the present disclosure is directed to managing request routing functionality corresponding to resource requests for one or more resources associated with a content provider. A service provider can assign a set of DNS servers corresponding to a distributed set of network addresses, or portions of network addresses, for one or more identifiable domains. If the service provider receives requests to assign DNS server to conflicting domains, the set of DNS servers for each identifiable are assigned such that there are no matching network addresses between the sets of domains associated with the conflicting domains.

Abstract: A system, method, and computer-readable medium for request routing based on client location information are provided. A content delivery network service provider receives a DNS query from a client computing device. The DNS query corresponds to a resource identifier for requested content from the client computing device. The content delivery network service provider transmits an alternative resource identifier in response to the client computing device DNS query. The alternative resource identifier is selected as a function of client location information. The client location information is obtained from information corresponding to a mapping of at least partial IP addresses to known locations. The client computing device then issues a second DNS query to the same content delivery network service provider. The content delivery network service provider can then either resolve the second DNS query or transmit another alternative resource identifier.

Abstract: A system and method are disclosed for automatically detecting associations between particular sets of search criteria, such as particular search strings, and particular items. Actions of users of an interactive system, such as a web site, are monitored over time to generate event histories reflective of searches, item selection actions, and possibly other types of user actions. An analysis component collectively analyzes the event histories to automatically identify and quantify associations between specific search strings (or other types of search criteria) and specific items.

Abstract: Generally described, the present disclosure is directed to managing request routing functionality corresponding to resource requests for one or more resources associated with a content provider. The processing of the DNS requests by the service provider can include the selective filtering of DNS queries associated with a DNS query-based attack. A service provider can assign DNS servers corresponding to a distributed set of network addresses, or portions of network addresses, such that DNS queries exceeding a threshold, such as in DNS query-based attacks, can be filtered in a manner that can mitigate performance impact on for the content provider or service provider.

Actions of users of an interactive system, such as a web site, are monitored over time to generate event histories reflective of searches, item selection actions, and possibly other types of user actions. An analysis component collectively analyzes the event histories to automatically identify and quantify associations between specific search strings (or other types of search criteria) and specific items. As part of this process, a decay function reduces the weight given to a post-search item selection event based on intervening events that occur between the search event and the item selection event.
