&lt;p>The internet is a critical technology infrastructure for almost two thirds of the global population. We use the internet for personal, civic, commercial and professional activities. Failure of the internet would majorly impact how our societies, lives and work is organised. While a total global collapse of the internet is unlikely, major disruptions may arise. Three aspects are key in understanding of how this could materialise: the underlying technological infrastructures, which are evolving with time; the fact that tech companies are increasingly shaping the Internet architecture to seek new commercial strategies; and the increasing control of the digital sphere for political reasons.&lt;/p>
