1. A method for identifying network infrastructure issues, the method comprising:
detecting a change to a network infrastructure;
in response to the detected change, receiving one or more performance indicator values from network components along a route through the network infrastructure including a network component where the change occurred;
receiving one or more preceding performance indicator values of the network infrastructure preceding the change;
generating a predicted network performance comprising one or more predicted performance indicator values on at least the one or more performance indicator values and the one or more preceding performance indicator values;
receiving one or more additional performance indicator values;
identifying a degree of deviation between the one or more predicted performance indicator values and the received one or more additional performance indicator values by comparing the one or more predicted performance indicator values and the one or more additional performance indicator values; and
in response to the identified degree of deviation exceeding a predetermined threshold, determining a network infrastructure issue.
