Edge DNS With an Anycast Network

Azion products are built with distributed and redundant architecture in different layers, and we are constantly looking at ways to improve the availability, performance and security of our products and services.

Edge DNS has a global infrastructure and an anycast network. In other words, queries that require DNS resolution are routed to the part of the globe and point of presence closest to the user.

What will change?

As we work in different market sectors, access peaks are unpredictable. So we opt to maintain a lot of capacity and redundancy in our architecture, so that in each point of presence there are redundant servers.

We always have two distinct domains available - ns1.aziondns.net and ns2.aziondns.com. To mitigate even failures in external DNS Root Servers, which are part of the domain resolution process, we already offered the redundancy, availability, performance and security necessary for your applications.

As we are extending our Anycast network, and adding the domain ns3.aziondns.org, we now have even more redundancy available in our DNS query resolution layer, which has positive implications for the availability of your applications hosted with Azion.

What Do I Need to Do?

In order for your zones hosted with Azion to take advantage of this additional Name Server you must make an addition to your DNS Registry (Registro.br, GoDaddy, AWS Registrar, etc.).

It is important to check that all your records are definitely registered and tested in Edge DNS before doing this. If you don’t, you run the risk of a loss of service.

Azion recommends using all available Name Servers, as this ensures the security, availability and performance of applications hosted with us.
