DNS may seem like something you set up right once and don't need to look at again. But changes need to be made regularly. And small mistakes can have major consequences.
The 3 most common DNS errors
Here you can read which DNS errors occur most often in practice, how to recognize them, and above all, how to prevent them.
1. Wrong TTL settings
A Time-To-Live (TTL) determines how long a DNS record is cached. Too high? Then it takes hours for changes to take effect. Too low? Then your DNS is queried unnecessarily often, affecting performance.
2. Incorrect DNS records
A mistyped CNAME record or a wrong IP address in an A record and your website or email is down. This happens more often than you think, especially with manual changes.
3. No logging or version control
Who made the change? When did it happen? Without logging and monitoring, you are completely dependent on memory and guesswork when something goes wrong.
