There are many components to a domain registry system. For example, we operate an EPP service which allows our many registrars to register and manage domains on behalf of their customers. That EPP server connects to our primary registry database which stores all the information about the millions of domain names that we manage. Behind the EPP system there’s a large and complex Shared Registry System (SRS) which manages the domain name lifecycle, processes transfers, renewals, and other out-of-band functions. We also operate a number of systems which allow our registry partners to have real-time access to the performance of their TLDs. We also operate Whois and RDAP services to allow third parties to access information about registered domain names.
But the most important part of our operations is our authoritative DNS service: without this system, none of the domain names registered in our database would actually work. Our DNS system has to be up and running 24 hours a day, 365 days a week – without even a second of downtime!
