A distributed delivery network for capacity enhancement of a communication link shared by multiple communication devices for network access service. The distributed delivery network may include one or more distributed storage devices, some of which may include at least one rotating disk storage device, a network interface, and one or more environmental sensors. Each distributed storage device may monitor data from the environmental sensor(s) and transition between an active state where messages are stored in or retrieved from the storage device, and a standby state where access is suppressed. The distributed storage devices may self-organize control operations for the distributed delivery network including message storage and retrieval and redundancy of messages, which may be determined by frequency of requests for the messages.
