A system for communication network management of a utility grid includes a database configured to store a grid information data set, where the grid information data set includes network device information for the utility grid and a network management system executable by a processor to: receive an event message from one or more network devices indicative of one or more failures in a communication network of the utility grid; retrieve the grid information data set; identify one or more network device associated with the one or more failures based on the grid information data set; transmit a request for a response to the identified one or more network devices; determine a response pattern based on responses from the identified one or more network devices in order to identify a cause of the failure based on the response pattern.
