The Domain Name System (DNS) lays the groundwork for using internet on your devices. Therefore, when the Spectrum DNS server is down or not responding, it most certainly is a bad day.

DNS serves as a translator between human and machine. You open a browser and type a domain name, such as “google.com”; while this domain name is easily readable by you, it’s not the same way for your computer.

How to Solve Spectrum DNS Issue

The DNS for Spectrum converts the human-friendly domain name to a computer-friendly IP address – a series of numbers required to locate the website. If this translation process fails, you cannot access the requested page.

Getting to the important part - how to solve the Spectrum DNS issue and restore your browsing privileges? Simply abide by this troubleshooting guide.

How to Resolve the Spectrum DNS Issue?

There’s no exclusive DNS server isn't responding fix. You could be merely facing a connectivity issue and misperceiving it as a problem with Spectrum’s DNS system. Therefore, eliminate all other possible glitches by practicing these steps:

  • Reboot your modem and router
  • Restart your device/computer
  • Check for loosened or damaged cables

Once you’ve covered the basics, and if the problem persists, move forward with advanced DNS troubleshooting:

Clear up DNS Cache

The DNS cache helps load websites quickly and reduces strain on the Spectrum DNS server to repeatedly cater to requests for the same web page. However, clearing the cache from time to time is necessary to prevent DNS errors.

Websites undergo changes over time like adding new content and design upgrades, which do not reflect in the DNS cache version. Clearing the cache allows the DNS server to load the latest version of the website, as well as get rid of performance and security concerns.
