Brace yourself for no internet in next 48 hours as a global internet shutdown is likely to happen within 48 hours and internet users across the world might face widespread network failures for next two days.

The Internet Corporation of Assigned Names and Numbers (ICANN) – which is the organisation responsible for maintaining the registry of domain names and IP addresses is undergoing maintenance – which could lead to a global internet shutdown in next 48 hours. The ICANN stated that the maintenance includes an update in the cryptographic keys that help to protect the internet’s address book or the Domain Name System or just DNS.

Confirming the maintenance check, the Communications Regulatory Authority (CRA) stated that this step was necessary to ensure secure, stable and resilient DNS system across the globe to stop the upswing in number of cyber-attacks. However, it might not be a complete global internet blackout and the CRA clarified that “only some internet users might be affected if their network operators or Internet Service Providers (ISPs) have not prepared for this change”.

If you are worried about no internet for two days, ICANN has stated that only 1% of total internet users (over 36 million) will be affected by the shutdown. Also, if the ISPs have enabled prescribed system security extensions in their networks, the internet shutdown can be avoided. Yet, there could be some difficulties in accessing web pages or making any transactions in the next 48 hours for anyone.
