Techniques are described herein for providing hardware configuration updates relating to equipment nodes in a network using change messages. In embodiments, the techniques may comprise receiving a status update comprising status information for one or more equipment nodes, determining, based on the status information, one or more changes in status of the one or more equipment nodes since a prior status update, and generating a change message that includes the one or more changes. The techniques may further involve providing the change message to at least one second computing device, wherein the one or more changes is used to update aggregate data maintained by the second computing device.
