DNS Errors: The Hidden Network Threat Costing Businesses Time and Money
When the internet suddenly “goes down,” most people think it’s their router, Wi-Fi, or ISP. But as Adrian Cooney points out, in many cases, the real culprit is DNS — the Domain Name System.
DNS acts as the internet’s address book, translating domain names (like google.com) into the IP addresses that computers use to communicate. When DNS fails, your network simply can’t find where to go.
These errors can cause:
Internet access interruptions that halt productivity.
Website downtime — customers can’t reach your business.
Application failures, especially for cloud-based tools.
Email delivery issues and delayed communication.
For modern businesses that rely on cloud connectivity, even short DNS outages can lead to significant downtime and revenue loss.
Why DNS Issues Are So Hard to Detect
DNS problems often start small — an outdated record, misconfigured resolver, or malicious redirect. They can go unnoticed until customers complain or productivity plummets. Traditional network monitoring tools don’t always see DNS traffic issues clearly, which makes them even harder to troubleshoot quickly.
