Internet users across the world may undergo extensive network failures as the key domain servers are scheduled to experience standard maintenance over the next 48 hours.
According to a report by Russia Today, global internet users might experience network connection failures as the main domain servers and its related network infrastructure will be down for some time.
The Internet Corporation of Assigned Names and Numbers (ICANN) will execute maintenance work during this time period by changing the cryptographic key that helps protect the internet's address book or the Domain Name System (DNS). This has been necessitated to counter the rising incidents of cyber attacks, the ICANN said.

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.
Internet users could face troubles in accessing web pages or making any transactions in the next 48 hours. Likewise, users could face inconvenience accessing the global network if they use an obsolete ISP.
