We present a system that visualizes the evolution of the service provided by one of the most popular root name servers, called K-root, operated by the RIPE Network Coordination Centre (RIPE NCC) and distributed in several locations (instances) worldwide. The system can be used either to monitor what happened during a prescribed time interval or to observe the status of the service in near real-time. The system visualizes how and when the clients of K-root migrate from one instance to another, how the number of clients associated with each instance changes over time, and what are the instances that contribute to offer the service to a selected Internet Service Provider. In addition, the visualization aims at distinguishing usual from unusual operational patterns. This helps not only to improve the quality of the service but also to spot security-related issues and to investigate unexpected routing changes.\ud
