Network monitoring services typically do not collect signal or data regarding the state of connectivity between end-user devices on a network segment and their serving access points. Identifying that a network device is up does not guarantee that end users have network connectivity. The practice of only monitoring infrastructure devices results in service outages being identified only through end-user reporting. This disclosure describes a network service that measures end-user connectivity via active requests and responses. Valid end-user addresses are loaded, grouped by network type and device, and sampled for connectivity at periodic intervals. If the fraction of responding end-user devices falls below certain thresholds, network operations personnel are alerted.
