Upgraded to Anycast DNS

07/01/2010 16:37

We are now on a highly scalable anycasted DNS network with 13 locations around the world! what this means for you is faster response times (as low as 7ms) and it eliminates the possibility of DNS denial of service attacks.

SwiftLayer now offers Anycast DNS (also called IP Anycast Routing) free to all customers using SoftLayer’s DNS servers. Anycast DNS is a high availability and geographically diverse advanced routing solution that allows multiple server destinations to share the same IP address and routes IP requests to the best destination based on network conditions. This enterprise-class feature increases uptime, provides exceptional opportunities for optimizing traffic flow, improves network performance, and maintains service redundancies. Previously, this functionality has not been available to organizations of all sizes as it is difficult to build in-house and very expensive to purchase from third party providers.

How it works:

By allowing multiple destinations to share the same IP address, Anycast DNS routing permits DNS registration information to be mirrored on server clusters either locally, regionally, or globally. Requests for the IP address are routed to the closest destination with the highest availability, preventing requests from being routed to a server that is unavailable or experiencing unusually heavy traffic.

Key advantages include:

Service Continuity — helps maintain uptime in the event of service interruptions
Network Protection — provides a comprehensive network failover solution
Disaster Recovery — allows critical services to be continuously maintained
