In one implementation, a call home system comprises a configuration engine, a cluster engine and an assignment engine. The configuration engine can identify a plurality of potential call home devices. The cluster engine can group a plurality of compute devices into a plurality of clusters. The assignment engine can assign a master call home device to each cluster. In another implementation, a method for calling home can comprise broadcasting a first message, receiving a response from a call home master associated with a cluster, and selecting a group identifier to append to a second message.
