Claim:
A system for network outage assessment, comprising: a processor; a user interface; and an outage tool that, when executed by the processor, retrieves a scheduled site list from a network management interface for a data network, wherein the scheduled site list specifies sites associated with the network management interface that are scheduled to be active and sites associated with the network management interface that are scheduled to be inactive, retrieves a plurality of communication site lists from a plurality of gateways associated with the network management interface, wherein each of the plurality of communication site lists is associated with a corresponding one of the plurality of gateways and specifies sites that are in communication with the corresponding one of the plurality of gateways and sites that are lacking communication with the corresponding one of the plurality of gateways, identifies a list of outage sites based on sites that are listed, in the scheduled site list, as the sites associated with the network management interface that are scheduled to be active and based on sites that are absent from the sites that are listed, in the communication site lists, as being in communication with the corresponding one of the plurality of gateways, and outputs outage site data based on the list of outage sites to the user interface to enable a management action, wherein the management action identifies at least one of a network element in a path of network elements from the network management interface to a site on the list of outage sites and a connection to the network element.
