We are happy to report that NS1.EASYDNS.COM has been redeployed as a four-node anycast cluster with the following nodes:
- Chicago, Illinois
- San Jose, California
- Amsterdam, Netherlands
- Tokyo, Japan
What does this mean? For starters, the IP address of NS1.EASYDNS.COM is now 18.104.22.168, the old NS1 (in the Q9 datacenter in Toronto) is still answering queries and will be amalgamated with the other Q9 nameserver node: REMOTE2.EASYDNS.COM
Next, anycast provides a couple of benefits which further add to the reliability and performance of the easyDNS nameserver cluster. All nodes in the strand respond to the same IP address, the node which is “closest” (in network topology terms) should respond to the querying servers, adding speed to initial DNS resolution and providing a further layer of redundancy during network outages and associated phenomenon (like DDoS attacks).
With the deployment of NS1 as an anycast strand, combined with the nameservers deployed on the Prolexic anti-DDoS cleanpipe as well the NS6.EASYDNS.NET round-robin cluster, brings our nameserver cluster to nearly 20 nameservers deployed over 6 nodes in Canada, USA, the UK, The Netherlands and Japan (stand by for Hong Kong any day now) with at least dozen being active at any given time.
