Without them, if your website, email or any other service that uses DNS goes down, it could (in certain cases) make it difficult to get it back online.

Typically DNS will need to be changed if someone has a new website built, decides to switch to a different email provider or include another online service or feature to their business. If a change is needed, it’s always important to save the records by taking a screenshot or exporting the ‘zone file’ before making any changes.

In fact, I have developed a piece of software which monitors DNS for changes. It’s not used particularly often but when it is, it’s immensely useful when helping our customers. Sometimes mistakes are made and it’s good to have a DNS backup to see what’s changed and identify the problem.
