MULTIPLE-MASTER DNS SYSTEM

In one particular example, a data communications system addresses changes in server load and/or connection latency in connection with data communication services provided through DNS master and slave servers. The system provides dynamic information routing, via a set of DNS master servers being in a multi-master configuration and including a first master DNS server and a second master DNS server, and consistency of DNS records is established between the master servers. Subsequently, the first DNS master server enters into an isolation mode in which updates are not communicated via the network. A set of isolation rules, which indicate how DNS records are to be updated in a communications network, are accessed and used in response to the network connections becoming reliable and the first master server updates the DNS records according to the rules, thereby establishing consistency between the first and the second DNS master servers.
