1. A computer-implemented method for cellular network outage detection, the computer-implemented method comprising:
receiving requests for connection to a cellular network from a plurality of mobile devices over the cellular network;
monitoring error rates for authorization requests exchanged between a network gateway connected to the cellular network and an authorization node for a first time period, the error rates including rates of denial of service messages from the authorization node to the network gateway;
determining a threshold error rate for the authorization node based on the error rates monitored during the first time period;
detecting an excessive error rate for the authorization requests between the network gateway and the authorization node during a second time period subsequent the first time period, the excessive error rate being in excess of the threshold error rate; and
in response to detecting the excessive error rate in the second time period, executing an override rule that includes stopping the authorization requests between the network gateway and the authorization node.
