The smooth functioning of the DNS or Domain Name System is crucial for guaranteeing uptime and optimum performance of a website. This is true for any website, irrespective of the site being hosted on a dedicated server or on a shared web hosting service. Even if the whole infrastructure of the web server is working perfectly, a DNS problem can give rise to an unresponsive site. Therefore it is necessary to include a DNS monitoring strategy in a company’s website monitoring goals so that there is consistent online visibility of the site. By making sure that the DNS for the site is working perfectly, it is possible to make sure that the end user experience of the website is positive.
The DNS plays a crucial role in translating a website name that a person uses into an IP address of web server that the computer systems use to find the location of the website on the Internet. When a web user sends a request for opening a website by typing the name of that site in the browser Hayden Hurst Youth Jersey , its DNS infrastructure directs it to the IP address of that web server.

Therefore, proper working of the DNS for a website is extremely crucial for making sure that the website is visible to the customer or end user.

The net result is that the users experience a website downtime.
Latency in The DNS Resolution

In case DNS cache is not able to serve the request for the site, it has to try and get the request passed through the other servers. This eventually leads to latency of the DNS resolution. Overloading of the DNS server can also lead to the latency of the DNS requests.
