We have our own servers farm for DNS hosting which consists of six powerful servers with PowerDNS and MariaDB. Our DNS uses native MySQL replication which allows us to decrease DNS propagation time after zone is updated. When you click «Apply changes» in the DNS manager, all the servers getting updated values in a Milli-seconds.
