Simple ways to improve your DNS resilience and security: #1 Redundancy

risk management

When providing DNS nameserver services a degree of redundancy is needed. In most cases the DNS records for a particular domain will be hosted by at least two nameservers, but is that enough by itself? When building a resilient system the risks involved with the failure modes of the system need to be considered and weighed up against the associated costs and overheads. As a common example - does having both DNS servers on the same local network segment provide you with protection against network failure? Probably not.

All Janet services are governed by the Janet policies. As a minimum, Janet recommends that you run your primary nameserver within your organisation, and use a secondary off-site. Many organisations connected to Janet have reciprocal arrangements regarding the provision of off-site secondary nameservers, but if that is not suitable then Janet can arrange for the Janet Network Operations and Service Centre to provide this service for you.
