DNS Latency 101 – Keeping it Low is the Way to Go

by | Jun 16, 2020 | Cloud Computing, Web Hosting

In the wonderful world of the internet, being online makes things so much easier for the most part. We can communicate with people all over the world, go shopping for things far away, watch videos on video streaming platforms and so much more. The internet has changed the world in so many ways and has seemingly made it so much simpler. If you don’t plan to dig up the way the internet works, it will stay simple. However, when you plan to run a business and have a whole network set up, there will be things that will surface and may cause confusion.

One of these things is DNS latency. For some, this may be a familiar term, as latency appears often in internet speed tests. Latency is an online network term that refers to the speed it takes a package to get from the source to a destination, and back. Latency is based on the server location, and a lower latency number is always better to have. Low latency means less data packets lost per transfer, and this results in a faster and more seamless connection with the other party through the server. This article will discuss why a low DNS latency is important in running your business:

Low DNS Latency Gives A More Stable Connection To Your Customers

DNS latency should be low to give your customers or site visitors the best experience. Nobody likes slow webpages or slow internet connections, so it is good to have your latency as low as possible to make browsing your pages easy. When you are operating an online retailing business, you will need a way to keep the latency down to communicate with your customers seamlessly without drops or lagging. These things would otherwise irritate your buyers and they may write you off from their lists of reputable sellers.

What Are Some Causes Of High DNS Latency?

High DNS Latency can often be associated with server locations. If you are hosting a website domain, it is best to get a provider closest to your location or the nearest server available from another country. This means that the distance between packet transfers is less and often gives a lower latency for you to communicate with your customers efficiently.

Using wireless networks for communication such as LTE over fixed-line networks is going to increase latency due to the signals coming from satellites, which are often unstable. If you plan to have better connectivity, use wired networks over wireless or data networks.

Malicious DNS traffic can also cause DNS latency to spike. Things like PRSD attacks that trigger high recursion, bots, malware queries, and C&C queries can all disrupt the DNS cycles on a server, causing high latencies.

What Should I Do To Keep Latency Low? 

When choosing a domain, choose a server provider that is closest to you or your area of operation to have the best possible packet transfers for low latency. Remember that the closer your server is to where your business is based will provide for better connectivity with clients and customers.


DNS latency is quite complicated to deal with at first, but if you are not well versed in the language of the internet and online connectivity, consult the services of a professional. It is still important to take note of things like this, as it will assist you in further optimizing your business for better growth and engagements.
