A computer-implemented method is operable in a content delivery framework having a network comprising multiple service endpoints running on a plurality of devices. A plurality of the service endpoints comprise a peer group. Each node in the peer group has at least one kind of responsibility. The method includes receiving a request at a first node in the peer group, wherein the nodes in the peer group are ranked hierarchically, and wherein the first node has a first rank in the peer group; and, based on a kind of responsibility the first node has for the request, attempting to process the request using a second node in the peer group, wherein the second node has a second rank in the peer group distinct from the first rank of the first node.
