Press Releases

CIRA’s D-Zone Anycast service is a resilient Anycast DNS cloud. This Anycast DNS (Domain Name Servers) set-up enhances an organization’s external DNS name resolution, but also adds in a layer of DDoS protection when an organizations DNS Servers are targeted. Built into the D-Zone service is the high reliability of the D-Zone Anycast cloud. These DNS are located in Canada, as well as global internet hubs. Each node is built to be a fully redundant, load-balanced service improving capacity, latency security and 100% up-time SLA.

In an Anycast DNS cloud, when one DNS name server goes down, it is automatically removed from the routing tables. DNS resolution remains fully available as the CIRA D-Zone leverages two separate Anycast clouds. An Anycast cloud is more resilient to a DDoS attack than a standard unicast DNS server, as it uses geo-location to specify which name server answers a query, as well as levering the combined bandwidth of all the servers.
