Picture this: you wake up, reach for your phone, and… nothing. No messages, no news feed, no banking app. The little spinning wheel of doom just keeps spinning. For a few terrifying hours last July, that nightmare became reality for millions of people around the world.
A single faulty line of code pushed out by a major cybersecurity company brought roughly 8.5 million Windows machines to their knees. Airlines grounded flights, hospitals postponed surgeries, and payment systems went dark. If one buggy update can do that, what happens when someone actually tries to break the internet?
The Hidden Fragility of the World Wide Web
We treat the internet like oxygen – always there, invisible, taken completely for granted. Yet beneath the slick apps and instant connections lies a shockingly delicate system held together by ageing protocols, concentrated corporate power, and miles of cable lying on the bottom of the sea.
In many ways, the internet still runs on 1990s technology designed in a more innocent era. The people keeping crucial pieces of open-source code alive often do it as a side hobby. And almost everything now depends on a handful of American cloud giants. One sneeze in a Virginia data center can give half the planet a cold.
The Physical Thread That Holds the World Together
Roughly 99% of international data travels through undersea fiber-optic cables – about 550 of them criss-crossing the oceans. These are not some sci-fi shielded super-tubes. They’re bundles of glass strands roughly as thick as a garden hose, wrapped in steel and plastic, lying on the seabed.
Ship anchors rip them up with depressing regularity. Fishing trawlers snag them. Earthquakes snap them like twigs. And yes, state actors have already shown they’re willing to cut them deliberately – remember the repeated “accidents” in the Baltic recently?
Repair ships take days, sometimes weeks, to reach the break. Each cable carries terabits of data per second. When several go down at once, entire countries can lose most of their international bandwidth overnight.
When a cable is cut, it’s not like flipping a backup switch. Traffic has to be rerouted across whatever spare capacity exists – and there often isn’t enough.
The Cloud Paradox: Convenience Creates Vulnerability
Twenty years ago, every company ran its own servers in its own basement. Painful, expensive, but also resilient – if one bank went down, the rest of the world kept spinning.
Today we’ve outsourced everything to a tiny oligopoly of cloud providers. Amazon Web Services, Microsoft Azure, and Google Cloud dominate the market. Thousands of services you use every day – from Netflix to your thermostat – ultimately rent space in the same handful of buildings.
That concentration creates god-tier efficiency right up until the moment something goes wrong. A misconfigured firewall rule, a certificate that expires at exactly the wrong second, a regional power blip – suddenly huge chunks of the internet vanish in perfect unison.
- October 2024: a networking glitch in one AWS region took down ChatGPT, Reddit, and half the smart-home gadgets in America.
- 2021 Fastly outage: a single customer’s bad configuration knocked BBC, CNN, Twitch, and the UK government offline for an hour.
- 2022 Cloudflare DNS failure: dozens of major crypto exchanges and gaming platforms disappeared simultaneously.
These aren’t rare black-swan events anymore. They’re Tuesday.
Internet Exchange Points – The Unsung Chokepoints
Even within countries, traffic funnels through surprisingly few physical locations called Internet Exchange Points (IXPs). Think giant warehouse rooms filled with routers where networks hand data to each other.
There are thousands of these facilities worldwide, but a couple of dozen handle the lion’s share of traffic. London’s LINX, Frankfurt’s DE-CIX, Amsterdam’s AMS-IX, and a few American hubs are absolutely critical. A fire, flood, or targeted attack on any one of them can black out enormous regions.
In 2022 a fire at an OVH data center in Strasbourg took huge swathes of the French internet offline. No conspiracy, no cyberweapon – just bad luck and worse fire suppression design.
The Protocols That Time Forgot
Then there’s the software layer. The internet still relies on protocols written when the biggest security worry was prank-loving grad students.
Take Border Gateway Protocol (BGP), the system that tells data which path to take between networks. It basically operates on trust. Anyone can announce “Hey, I own this chunk of the internet!” and if enough routers believe them, traffic gets diverted – sometimes into oblivion, sometimes straight to intelligence agencies.
Pakistan accidentally knocked YouTube offline for most of the planet in 2008 trying to block it domestically. China regularly “borrows” huge blocks of IP addresses. Russia has tested disconnecting its entire national internet from the global one – and they’re getting better at it.
The Rising Risk of Deliberate Sabotage
So far most global outages have been accidental. But accidents are excellent dress rehearsals.
Intelligence agencies already map undersea cable landing sites. Drone submarines exist that can tap or cut cables undetected. And state-backed hacking groups have shown they can persist inside critical infrastructure for years.
Imagine a near-peer conflict in which the opening salvo isn’t missiles but coordinated attacks on cables, cloud regions, and IXPs. Financial markets would freeze. Logistics would collapse. Emergency services would go blind. Modern war could be over before the first tank rolls.
The internet was built for resilience against nuclear attack, but it was never built for the level of dependence we have now.

What Would Actually “Break” the Internet?
Total apocalypse is unlikely. The internet is a network of networks; it routes around damage by design. But a functional breakdown – where large parts of the world lose reliable access to banking, government services, supply chains, and communication for days or weeks – is becoming scarily plausible.
Here are the most credible scenarios experts worry about:
- Major coordinated cable-cutting campaign in the Atlantic or Pacific
- Successful attack on root DNS servers combined with BGP hijacks
- Catastrophic zero-day exploit in widely used cloud control planes
- Solar superstorm frying unshielded satellite constellations and power grids (yes, really)
- Regulatory or technical “sovereign internet” fragmentation that accidentally breaks global routing
Can We Fix It Before It’s Too Late?
Good news first: engineers have known about most of these problems for decades. Solutions exist. Bad news: implementing them costs money, requires global cooperation, and threatens the profits of very large companies.
Still, here are the big ideas people are pushing:
- Modernize BGP with proper cryptographic authentication (Resource Public Key Infrastructure – it’s been “coming soon” for 20 years)
- Lay many more cable routes, especially avoiding obvious chokepoints like the Red Sea and the Luzon Strait
- Spread cloud workloads across genuinely independent providers and regions
- Build proper redundancy into consumer devices instead of hard-coding them to a single cloud endpoint
- Establish international norms treating internet infrastructure as protected civilian assets, the way we (mostly) protect hospitals in wartime
None of these are cheap or easy. But the cost of doing nothing keeps going up with every CrowdStrike-scale outage.
What This Means for Investors and Ordinary People
For investors, internet fragility is creating an entire shadow industry: companies building private fiber routes, sovereign clouds, satellite backups, and mesh networks. Some of the less obvious winners might surprise you – think specialized repair-ship operators or the handful of firms that still make hardened on-premises hardware.
For the rest of us, the takeaway is simpler: the age of assuming the internet “just works” is ending. Diversify your banking. Keep some cash. Maybe even – whisper it – print out important documents once in a while.
The internet isn’t going to disappear tomorrow. But the era of treating it as an indestructible utility is already over. The only question left is whether we reinforce the foundation before the next big storm hits – or wait until the house falls down around us.
In my view, the scariest part isn’t the technology itself. It’s that we’ve built a global civilization on a system we never hardened for the level of reliance – and malice – it now faces. The fixes are boring, expensive, and require people to agree on things. Which means the clock is ticking louder than most of us realize.
