Performance measurements from a planetary-scale deployment against a real workload indicate that CoDoNS can provide low latencies for query resolution. Massive replication for the most popular records, but a modest number of replicas per server, achieves high performance with low overhead. Eliminating the static query processing hierarchy and shedding load dynamically onto peer nodes greatly decreases the vulnerability of CoDoNS to denial of service attacks. Self-organization and continuous adaptation of replication avoids bottlenecks in the presence of flash crowds. Proactive update propagation ensures that unanticipated changes can be quickly disseminated and cached in the system.
