Wide area network monitoring

A computer-implemented method for determining a network status of a network, the method comprising:

• receiving first routing data for a first network on a monitoring network, the first routing data comprising available routes through the first network, the first network located in a distinct autonomous system from the monitoring network;
• receiving, from a plurality of client networks, second routing data, distinct from the first routing data, on the monitoring network for the plurality of client networks, the plurality of client networks in communication with the first network, the second routing data comprising network routes from individual client networks, at least portions of the individual network routes traversing the first network;
• aggregating the second routing data for the plurality of client networks, the aggregated second routing data allowing a comparison of the network routes from individual client networks, the comparison indicating a status of the portions of the network routes from individual client networks traversing the first network;
• and
• determining a network health status of the first network based on the first routing data and the aggregated second routing data,
• said computer-implemented method performed by a computing system that comprises one or more computing devices.

A system for determining the network status of a first autonomous system, the system comprising:

• a router interface, the router interface located within a second autonomous system, and being in communication with one or more external networks, the router interface configured to receive first routing data for a first external network, the first routing data including reachability information for the first external network;
• a computing system comprising one or more processors and a second memory, the computing system in communication with one or more client networks distinct from the second autonomous system, the one or more client networks in communication with, but distinct from, the first autonomous system, the first autonomous system providing a communication route for the one or more client networks, the computing system configured to receive second routing data comprising network routes from the one or more client networks;
• and
• a monitoring module located within the second autonomous system, the monitoring module in communication with the router interface and the computing system, the monitoring module configured to:
• compare the network routes from the one or more client networks, the comparison indicating an operational status of the portion of the network routes traversing the first autonomous system;
• and
• determine a status of a portion of the first autonomous system based on the first routing data's reachability information and the status of the portion of the network routes.
