Distributed DNS system now available in all data centers

We have recently launched our distributed DNS system in all our data centers – in our US data center in Chicago, in our UK data center located just outside London, and in our Australian data center in Sydney.

Up until now, we have relied on one major DNS cluster of servers to take care of all DNS requests to the websites hosted with us. This cluster is located in our US data center. Over time, we have built identical cluster systems in the rest of our data centers as well. These server clusters communicate constantly, exchanging the latest changes in the DNS settings of your websites.

What will the distributed DNS system bring to the table? First, DNS redundancy. If there is a connection problem with any of our data centers, the clusters in the other two will pick up all the requests in an instant.

Secondly, if there is a request coming from Australia and the nearby region, the request will be picked up by our Australian data center and the DNS cluster there, and it won’t have to travel all the way to the US and back. And while this time is measured in milliseconds, the latter can be dedicated to boosting your website’s loading speed instead.
