Did you know that DNS is your domain's most critical service? We do! Here are some reasons why you should host your DNS at ETRN:

• Service Description: Our DNS Hosting Service provides reliable and secure authoritative-only^[1] name server service for your domain. An authoritative-only name server only returns answers to queries about domain names that have been specifically configured by the administrator. This is your domain's most critical service as all of your services depend on a reliable DNS service to function properly. This is the service that enables web browsers to find your website and enables e-mails servers to find your e-mail server.
• SLA: Our DNS Hosting Service is designed to provide 100% up-time when all 7 DNS servers are used to host the DNS for a customer's domain. What this means, is that 100% of the time, our system will be able to answer properly formatted queries for valid records in the customer's domain.
• System Status: The status of our DNS servers is publicly accessible and can viewed at any time at http://status.got-dns.com/
• Multiple Administrators: You can have multiple account administrators. Each account administrator can each have the own set of capabilities and domains that they can manage.
• Audit Logs: The system keeps a log of your (and your other account administrators') changes.
• Backup and Restore: The Backup and Restore option can be used to perform on-demand and scheduled backups of your data. Both local and wide variety of remote backup destinations are supported.
• This is how we achieve these results:
  • Separation of roles: The hosts customers access to manage their DNS are separate from the infrastructure that answers DNS queries.
  • Multiple servers: We fully understand that DNS is your domain's most critical service We don't cut corners by given our customers access to only 2 DNS servers, the minimum requirement imposed by most domain registrars. In fact our approach is quite the opposite, we provide each of our customers with access to 7 DNS servers, at no extra charge. Most registrars define 7 as the recommended maximum number of DNS servers servicing a domain. Each of the 7 DNS servers is on a separate physical host. A problem at at any one machine does not effect the ability of the others to answer queries. All 7 DNS servers are primary^[2] servers and can function indefinitely without any communication with any of the other DNS servers.
  • Consistent results: When an update is published to our systems, it is published to all of the hosts serving your domain at the same time. This means that you will see consistent results, query after query. You'll never have to wait hours for the system to synchronize.
  • Flexibility: We don't impose arbitrary restrictions on your DNS records. TTLs can be chosen to fit your needs. Virtually any DNS record type can implemented. We provide easy to use wizards to help with defining and editing your DNS records. For advanced users, direct access to the underlying zone file is also provided.
  • Multiple physical locations: Our DNS is currently hosted from four separate data centers, three in the US and one in the UK. An outage at any of these locations does not effect the other locations' ability to answer queries.
  • Multiple networks: Each location is serviced by different connectivity providers. This prevents a network outage at any one location from effecting the connectivity at another. Since each location is serviced by multiple providers, this also improves the performance of the service and reduces response time.
