NEW DELHI: It is reported that Internet users around the world may experience network connection failures. This will be a result of main domain servers and related infrastructure controlling the web will be powered down for some time.

The Internet Corporation of Assigned Names and Numbers (ICANN), which is responsible for maintaining the registry of domain names and IP addresses, will be changing the cryptographic key that helps protect the Domain Name System (DNS) or the internet’s address book.

According to the Communications Regulatory Authority (CRA), It’s an important measure to ensure 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 said.

Analyst from the Mobile Research Group Eldar Murtazin told RT that internet users may face some difficulties within 48 hours. There may be problems with access to some resources, and slow loading of internet pages. Some users may have problems with access to the network if they use an outdated provider.

The procedure for changing cryptographic keys has become necessary as a result of rising threats for the internet infrastructure.
