8 steps to better DNS


DNS is essential to the operation of all aspects of the internet and modern digital businesses. DNS is a highly available, highly redundant, highly reliable service that is absolutely essential to your company’s applications and business operations. A failure in your DNS can bring business to a halt, jeopardizing your company’s future.

The problem with DNS is that a tiny mistake in a configuration file can have a ripple effect through the entire DNS and impact all aspects of your company’s operations. A DNS failure will impede your customers’ ability to use your products and your company’s ability to make money. Without solid DNS configuration management in place, you make yourself vulnerable to simple but costly mistakes.

DNS changes are so common and so simple that they are rarely considered risky business operations. For smaller organizations, the development team probably manages its own DNS servers or has some other way to make DNS changes on the fly. As organizations get larger and more complex, the number of DNS servers and the number of people who can make changes to them tend to multiply.

With so many people making changes, it’s not surprising that something goes wrong occasionally. In fact, it would be more surprising if things didn’t go wrong.

DNS outages are caused by a variety of factors, including human error, software issues, and hardware failures. But the most common cause of DNS outages is incorrect configuration files being deployed to DNS servers.

What steps can a smaller company that lacks quality DNS hygiene make in order to put a high-quality DNS management process in place? Here are eight things any company can do to improve its overall DNS quality to keep applications operational and healthy.
