Embodiments are directed a system that monitors a plurality of relevant network conditions of a wireless cellular network. Over time, the system records a plurality of network snapshots based on the monitoring. Each network snapshot reflects a status of each applicable network condition at a respective point in time at which the snapshot was recorded. The system then generates a respective visual network topology map for each network snapshot through which the status of each network characteristic at the point time at which the snapshot was recorded is accessible. The system connects together each network snapshot resulting in a visual chronological historical record of the status of the network at each point time at which the snapshot was recorded reflected by each respective network topology map.
