Conventional replication status reporting techniques in a Content Delivery Network (CDN) tend to produce large, unwieldy reports which are difficult to transmit, consume large amounts of bandwidth, and require a large share of CPU resources to process. A replication status reporter which identifies an ordered list of events corresponding to content items (files) for replication (pre-positioning) in a content delivery network, and determines a point of progression along a sequence represented by the ordered list of files, allows a management server to avoid computationally expensive endeavors which itemize and transmit lists of every replicated file in the CDN. The servers in a CDN channel receive files as a series of ordered events. Origin servers deliver the files generally according the event. A replication status report indicates the progression in the list, rather than enumerating the entire list, avoids cumbersome and unnecessary processing and delays in reporting replication status.
