A method for updating real-time data between intervals in a communication processing center, having a data source and a data collector, includes receiving, at the data collector, real-time data at intervals from a data source. The real-time data includes information on the availability of aspects of a communication network. The received real-time data is stored in a memory. The occurrence of a specified triggering event between the intervals is detected. The stored real-time data is updated based on information relating to the specified triggering event.
