The internet has become an irreplaceable tool across most of the globe, serving as the backbone of commercial operations and e-commerce, worldwide news and social media commentary, as well as health and public welfare.&nbsp;

We take the internet for granted when it functions well. It's similar to breathing. We don't think about it, or the procedure that goes on behind the scenes.&nbsp;

But once it stops working, then we realise the authority of its presence in our daily life. The internet is becoming more and more centralised. As a result, it has become more vulnerable to catastrophic breakdowns.
