Introduction: The Importance of DNS in Today’s Digital Ecosystem In today’s digital world, a business’s online success relies heavily on a strong infrastructure. At the heart of that infrastructure is DNS (Domain Name System). DNS acts like the internet’s phonebook which translates easy-to-remember domain names (like www.example.com) into machine-readable IP
It’s extremely important that visitors to your site are able to reach the content they want, and within a reasonable amount of time. DNS monitoring is the first step in ensuring consistent performance and connectivity.
The new DNS caching features at Dotcom-Monitor allow you to perform some interesting tests that show how DNS caching can affect your page load speed.
We realize that many organizations monitor their online services with a number different goals in mind, and so we listened to the feedback we received that some users want to include the DNS response time in their monitoring and some users want to be able to remove DNS response from their monitors.
How you wish to handle DNS response time in regard to your monitoring needs is up to you, but we want to take this opportunity to show the differences in how DNS response time affects website load using our new tools.
We ran a test monitoring YouTube from a single location in the midwest United States with three different DNS cache settings. A basic HTTP full page load on the YouTube front page resulted in some interesting, although not that surprising results.
Keep in mind the results will vary depending upon a number of variables such as which locations you are monitoring from, the time of day, the load on the DNS servers, and on the website servers.
For George, the clean-up is just beginning. He is not even yet aware that his domain is blacklisted. All he knows is that he can’t send out additional emails, the update email on the company party that evening is now a fire-drill, and his boss is giving the system administrator and him the stink eye. The problem of not knowing for hours that your site has appeared on a DNS Blacklist (DNSBL) and that email—and, even worse, potentially website visitors—are being rejected is a problem with both primary impacts and multiple secondary impacts.
