The DNS or Domain Name System is a service that translates human-readable hostnames (such as indianexpress.com) into original, numeric IP addresses. If the DNS is not working properly, your computer will not be able to connect to the servers that host the website one is looking for. But the problem is deep and it is integrated with BGP routing.
