A method and apparatus for automatically localizing failures in a network. Failures can be localized by receiving an observation, querying a database for a plurality of models of risks and calculating a hypothesis from the plurality of models of risks that explains the observation. The observation comprises link failures reported by a plurality of data sources. The plurality of models or risks represents links that would likely be impacted by the failure of each component within the network stored in a Shared Risk Link Group (SRLG) database. A Spatial Correlation Engine (SCORE) applies an algorithm to calculate a hypothesis from the plurality of models of risks that explains the observation, thereby, automatically localizing failures in a network.
