Claim:
1. A computer-implemented method of determining performance of network paths, the method comprising: measuring a packet loss rate across individual ones of a plurality of network links in the network, wherein a network link includes at least two nodes; creating a set of path performance information by aggregating the measured packet loss rates across the plurality of network links; creating an adjusted set of path performance information by excluding the measured packet loss rates across a subset of the plurality of network links from the set of path performance information, wherein the subset is selected based at least in part on a statistical difference between the network links in the subset and one or more other network links of the plurality of network links; determining a failure on one or more of a plurality of network paths based on the adjusted set of path performance information; determining nodes associated with respective customers; determining paths including the nodes associated with respective customers; and determining a network failure impact to one or more customers of the determined failure by calculating a percentage of the paths associated with respective customers determined to comprise a failure, wherein excluding the measured packet loss rate across the subset of the plurality of network links comprises:
