During our almost 11 year history we’ve maintained a 100% DNS uptime. Deploying many DNS servers in multiple locations has been key in providing such up time. An extension of this has been utilizing Anycast to provide higher availability, help reduce DNS latency and increase resilience to internet based attacks.
Visit the Wikipedia page about anycast if you’re interested in detailed information or are looking for alternative sleep aids.
DNS queries are routed to the data center closest to you or your customers, lowering DNS response times. This results in a faster loading site and better end user experience.
Fact: For every 1000 kilometers of fiber there are 10 milliseconds of delay
We are also able to perform maintenance without effecting service. DNS traffic is automatically rerouted to the next closest data center during a maintenance window.
Anycast also helps in minimizing the effectiveness of DNS directed DDOS attacks, since a single NS record is distributed across multiple locations, servers and bandwidth providers.
Since 2007, No-IP has been using IP anycast on some of our name server (NS) records. In the coming months all Managed and Backup DNS NS records will use anycast. Stay tuned as we keep you posted with our progress including other exiting features to be announced later this year.
