DNS Check – Why Regular DNS Checks Are Important
Running regular DNS checks is an essential part of maintaining a healthy, reliable online presence. DNS issues often develop quietly in the background and only become obvious once something breaks. By the time a problem is noticed, it may already be affecting customers, emails, or revenue.
A proactive DNS check helps identify and prevent common issues before they cause disruption.
Problems Regular DNS Checks Help Prevent
Emails Going to Spam or Not Being Delivered
Incorrect or missing DNS records such as SPF, DKIM, or DMARC can cause legitimate emails to be flagged as spam or rejected entirely. Regular DNS checks help ensure email authentication records are present, valid, and correctly aligned with your email provider.
Websites Loading Incorrectly or Going Offline
DNS misconfigurations can cause:
- Websites to load from the wrong server
- Visitors to see outdated content
- Complete website outages
Routine checks confirm that your domain still points to the correct hosting environment and that records haven’t been accidentally changed or removed.
SSL Certificate Warnings and Security Errors
SSL certificates rely on DNS for validation and trust. DNS changes, expired records, or incorrect hostnames can trigger browser warnings such as “Your connection is not secure”.
Regular DNS checks help spot issues that could break HTTPS, damage trust, and impact SEO rankings.
Why DNS Problems Are Often Missed
DNS failures don’t always happen immediately. Changes can appear to work for some users while failing for others due to caching and propagation. Without regular checks, issues may go unnoticed until customers report problems.
For businesses, this can mean:
- Lost enquiries
- Missed emails
- Reduced trust
- SEO and ranking drops
