A system and method for detecting or reporting service level or service outages on a network includes a meta service generator that operates on a network inventory to generate service definitions. The system is a server-based model, and each service definition includes usergroup and points of presence, thus instantiating multiple services in a manner that allows the definition to focus on relevant element events amid massive network event data, and detect service outages quickly and dependably. The outages, transaction spec outages and events so determined may be aggregated to provide overall measures that are compared with thresholds, performance criteria and other service metrics specified in a user Service Level Agreement (SLA) for billing, credit, evaluation or other purposes. Batch processing embodiments may operate with outage logs, and employ a concurrence algebra to correct outage intervals for planned and forced outages, providing a truer measure of performance that allows the system to generate multiple different reports reflecting different compensable or inconsequential outage states.
