MUMBAI: For the sake of updation and maintenance global internet users might experience network failures over the next 48 hours. In light of the maintenance work, internet users might face difficulties in accessing web pages or making transactions.

The Internet Corporation of Assigned Names and Numbers (ICANN) will carry out maintenance work to change the cryptographic key that helps protect the internet’s address book or the Domain Name System (DNS).

According to the experts, the change of cryptographic key will help prove as a necessary step for internet protection as the number of cyber attacks swell.

In a statement, the Communications Regulatory Authority (CRA) said the global internet shutdown is necessary for ensuring a secure, stable and resilient DNS. “To further clarify, some internet users might be affected if their network operators or Internet Service Providers (ISPs) have not prepared for this change. However, this impact can be avoided by enabling the appropriate system security extensions,” it added.
