Methods and systems for delivering content are described. A content distribution network may utilize multiple content sources and datacenters when delivering content to a requesting device. One or more service metrics associated with the content as it is being prepared for delivery at each of the datacenters may be monitored by a quality agent. The quality agent may use the one or more service metrics to select a distribution datacenter to deliver the content to the requesting device. The quality agent may instruct the remaining datacenters to disable delivery of the content to the requesting device.
