During the next 48 hours, internet connectivity may be affected across the world. The effect is due to maintenance work being carried out in key domain services. Some users may find their internet connectivity disrupted especially if their service providers have not adapted measures to deal with the change.
The Internet Corporation of Assigned Names and Numbers (ICANN), which is primarily assigned with the task of maintaining the registry of IP addresses and domain names will be engaged in the task of changing the cryptographic key that is instrumental in protecting Domain Name System (DNS) or what is essentially the internet’s address book.
In case you notice a slowdown in services or complete disruption, it would be safe to assume that your Internet Service Provider is not equipped to deal with the changes. Meanwhile, the ICANN has stated that a way to deal with the problem would be to enable suitable system security extensions.
