The internet may feel seamless and always-on, but according to a recent article in The Guardian, it rests on a surprisingly fragile foundation. Beneath everyday services like streaming, banking and smart-home devices lies an aging framework of data centres, undersea cables and vital protocols — many of which are concentrated in only a few providers.

 

 

For example, major data hubs in Virginia and Iowa — run by giants like Amazon Web Services, Google Cloud and Microsoft Azure — are critical to operations worldwide. This means that natural disasters, cyber-attacks or cascading software failures could trigger major outages.

 

 

The article outlines a “worst-case” scenario: a tornado takes out a data cluster in Iowa, a heatwave cripples a Virginia centre, and a cyber-attack hits Europe — creating a ripple effect that disables major cloud services, smart devices and online infrastructure. It emphasises that while the internet itself might technically still run (two networked devices connected still count), the services people rely on would vanish. Experts point to weak spots in key systems: DNS (“internet phone book”), BGP routing and the dominance of a handful of providers. Although a full collapse is improbable, the article argues we’re under-prepared for large-scale failures that expose how dependent society has become on digital infrastructure.

 

Key Takeaways:

 

Our global internet infrastructure is highly centralised and concentrated in a few providers and data hubs — creating critical single-points of failure.

 

A combination of natural disaster, cyber-attack or software glitch could cascade into widespread outages of everyday services — even if the “internet” technically remains connected.

 

While full collapse is unlikely, the scale of our dependency means we’re vulnerable and inadequately prepared for a major systemic disruption.

yes. There are some good graphics out there that show the major internet trunk lines such as undersea cables, satellite uplinks and down links. And that is just about the physical things.  The Huge network services now and the increasing reliance on the cloud is a recipe for disruption.   Just like previous civilizations, as things get more complex they can get more fragile and vulnerable

I cannot but agree.

 

Recent Chinese and Russian "grey zone" warfare activities prove how vulnerable underwater sea cables are to destruction.  The world only has a handful of vessels capable of repairing such damaged cables.

 

Data centres etc. are dependent upon constant electricity and clean water supplies - one missile or drone, large earthquake, massive typhoon/cyclone, an effective cyber attack, etc. could easily disable these essential facilities.

 

With analog systems being largely decommissioned, there is not backup system.

Won't take much to take down a banking infrastructure: online banking, ATM's, branch computers etc. Best to always keep some cash handy for emergencies.

Time to ask: Can you do without Internet? How long?
