Abstract

The present invention automatically monitors a Data Center Operations (DCO) network (or any LAN/WAN network) for circuit outages and sends a notification if an outage is detected. A console at a Remote Operations Center periodically pings a console at each Data Center (pinging may also be on-demand). The remote console receives responses from each pinged Data Center console. A response will be received for each possible route between the Data Center and the Remote Operations Center. These responses will indicate the route that was taken. The routes indicated in the responses are then compared with a table of routes previously identified as routes of concern or interest. Also listed in this table is a circuit identifier for each route. Any route listed in this table for which a response was not received is identified as unavailable. An automatic notification, such as a page, is then sent identifying this route by the circuit identifier.
