1. A method, comprising: receiving, at a first network node, data indicative of a plurality of relative lag times for instantiation of a specific content item at a first plurality of network nodes, the specific content item being common for each network node of the first plurality of network nodes; receiving, at the first network node, network performance data related to servicing a request for the specific content item for each network node of a second plurality of network nodes; receiving a request for the specific content item from at least one network node of the second plurality of network nodes; and selecting a second network node of the first plurality of network nodes to service the request for the specific content item, the second network node being configured based at least on the received network performance data and a first lag time for instantiation of the specific content item at the second network node with respect to a second lag time for instantiation of the specific content item at at least one other network node of the first plurality of network nodes.
