As an avid internet user, we love downloading movies, videos, music, software from the web. Mos of the times we least bother about the browsing speeds, other technical issues our ISPs doesn’t provide.
Get 50 Mbps download speed for Rs. 500 only – we come across these ads frequently. Such type of ads attracts us a lot. But while browsing the websites, the same high-speed broadband connections sever the pages poorly. If we questioned them, they simply say it is not their fault, and they start blaming the servers of websites.
Most of the times we encounter bad gateways, DNS errors. Poor DNS servers located at ISP’s are the primary culprit for problems. But they don’t change. Airtel, Idea, Act Fiber, Vodafone, BSNL all the popular ISPs around the world need to maintain DNS servers to resolve the websites correctly.
How ISPs show websites?
Here I will explain DNS resolving in brief. Every website has a dedicated IP address and all the data that site contains will be stored at that IP address in the hosting company. But remembering the IP is a hard task for ordinary men. So while creating websites, webmasters link their domain name with the IP address they are using. Once they created a link in between Domain name and the IP address, their task finishes. Now it is the responsibility for ISP’s to update that name, with its actual IP, in their DNS servers.
computerera.co.in is the domain name
220.127.116.11 is the IP address
So when you typed computerera.co.in in your browser address bar, the data from the 18.104.22.168 loads in the background. If your ISP DNS server is faulty or overloaded or not updated properly, you may get DNS errors while browsing the computerera.co.in website.
So, now you might be clear with why ISPs are creating issues while browsing the internet. Configuring the Google public DNS servers or other third-party servers will solve such problems to a certain extent.
Airtel Pathetic story
Now I discuss the Indian ISPs and the latest bitter experience I faced with them. To optimize & upgrade the server resources, I changed my server IP to the new one on 29th August 2016, 11 PM. Within 5 mins my website is live from US, UK, Australia VPN servers. After 30 mins, my Act Fibernet started to recognize my server new IP and started severing the site. But I failed to open site with my Airtel 4G mobile data until 30th August 2016, 10 PM. Not only Airtel, Idea, and few other ISPs also failed to reflect DNS records.
Surprisingly Reliance Jio started serving my website just within 2 hours. You can check the above screenshots captured one after another & confirm how worst Airtel is behaving after 20 hours of server migration.
For the end user and web developers, such type of incidents became familiar. But in the internet age, that too while comparing with the fast reflection from other companies ISP’s, the pathetic performance Indian ISP’s are showing is not excusable.
