Request routing management based on network components

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;
• and
• a computing system in communication with said data store and associated with a service provider, the computing system including a hardware component and operative to:
• obtain a first domain name service (DNS) query from a network component responsive to at least one resource identifier, the first DNS query corresponding to a resource associated with the resource identifier, and the network component providing the first DNS query on behalf of a client computing device in accordance with a first network scheme;
• and
• determine an alternative identifier responsive to the first DNS query from the network component, the alternative identifier to cause a second DNS query associated with the resource to be transmitted from the network component to a component associated with the service provider utilizing a second network scheme, and the determination of the alternative identifier being based on additional information provided in a DNS portion of the first DNS query.
