Abstract
Techniques for internet last-mile outage detection are disclosed herein. The techniques include methods for monitoring, by a network appliance associated with a network, a plurality of network nodes, detecting, by the network appliance, that a network node of the plurality of network nodes in a last mile of the network has disconnected from the network, overlaying, by the network appliance, the network node over a network model for at least a portion of the network including the network node to generate a model overlay, and determining, by the network appliance, a last mile outage source associated with a disconnection of the network node by identifying a lowest common ancestor node of the network node from the model overlay. Systems and computer-readable media are also provided.
