The internet, the linchpin of modern life, is held together by decades-old infrastructure that is increasingly vulnerable to catastrophic failure, experts have warned. A recent glitch at a datacentre in Virginia served as a stark reminder that the unthinkable could become reality.
Potential triggers range from extreme weather taking out key datacentres to cascading software crashes caused by AI-written code. Even a few targeted attacks on undersea cables could cause widespread disruption. The real doomsday scenario, however, is a sudden, snowballing error in the fundamental protocols that underpin the entire network.
Concentration of critical infrastructure is a major concern. A single tornado in Iowa could devastate a Google datacentre cluster, taking down YouTube and Gmail across the US and Europe. A heatwave in Virginia could knock out Amazon Web Services' 'datacentre alley', affecting countless services that rely on it.
Amid cost-cutting and automation, experts warn that the internet's resilience is being eroded. AWS, Microsoft and Google control over 60% of the cloud services market, creating a dangerous single point of failure. While the internet might technically survive such outages, the services people rely on daily would vanish.
In the aftermath, life would revert to a pre-digital age: chequebooks, landlines, and physical navigation. The question is not if this could happen, but when.
