If you are facing issues in the next 48 hours, there is no need to panic, it is because the Internet Corporation of Assigned Names and Numbers(ICANN) will be working on updating the cryptographic key to protect your Domain Name System(DNS). This has been necessitated to counter the rising incidents of cyber-attacks, the ICANN said.
If you are wondering what ICANN is? ICANN isa nonprofit Organization based in Los Angeles, California responsible for maintaining the registry of domain names and IP addresses on the internet.
Let us also have a quick look on what DNS is? The Domain Name System (DNS) is the phonebook of the Internet. When we access information online through domain names, like google.com or msn.com. Web browsers interact through Internet Protocol (IP) addresses. Every Domain name has its own unique IP address and DNS helps translates domain names to IP addresses so browsers can load Internet resources.
During the Cryptographic key update process certain websites, web pages and web based services and resources will be unavailable for certain duration of time since the process will happen in batches, it doesn’t mean that the entire internet will be shutdown. Once the new security measures are updated and authenticated, things should be back to normal.
As per ICANN’s estimates after initial tests, only 1% of the total internet users around the world are expected to be impacted by the shutdown. That would still calculate to more than 36 million people, at least, as per the numbers shared by the organization.
Please note that there is nothing we can do or your Internet Service provider can do if you are facing internet issues during the process of updation. All we can do is be patient and wait for the process to complete. If the issue still persist after the update, you could try restarting your router, it will help refresh the device and help accesses the DNS data updated by your internet service provider.
