Increase resiliency to DDoS attacks with the extra query capacity and bandwidth of the D-Zone Anycast DNS cloud. To the world, the cloud appears as a single IP address. In reality it is a network of geographically distributed nameservers. An anycast cloud is much more resilient to a DDoS attack than single unicast servers because it uses geo-location to specify what server answers a query and because the network has the combined capacity and bandwidth of all the servers. With anycast, the impact of an attack is isolated to the name server closest to the source(s) of the attack.

Additionally, the D-Zone architecture has redundancy at both the nodes and with a primary and secondary cloud to even further mitigate the impact of DDoS attacks. The net result is:

• DDoS attacks that originate off-shore are soaked up by the international nodes to mitigate the risk that hackers can bring down your website and services.
• DDoS attacks within Canada are soaked up by the local node that is geographically closest to the attack, protecting the rest of your Canadian traffic.
