How We Work

We have designed our DNS systems to be as fault tolerant as possible. Even if one piece of our infrastructure does go down we are still able to serve requests. We use replication techniques to instantly transport all new changes between multiple geographically diverse servers.

We've decided to offer this service free for everyone so that we can load and stress test our systems. We believe in our technology and the only way to ensure it will live up to our expectations is to allow the widest audience possible to test and use it. Our service supports the full DNS spectrum, from A records to SPF records, if you find any problems with our service please let us know.

Using our systems is as easy as setting your domains name servers to and and creating a few simple A and MX entries.
