How Centralization Broke the Internet: The Cloudflare Case

I didn’t wake up one day planning to have strong opinions about internet infrastructure. Like most people, I only really notice how the internet really works when it suddenly doesn’t.

That’s exactly what happened during Cloudflare’s recent global outages, when large parts of the web (including but not limited to social platforms, AI tools, business services, and even outage trackers themselves) became unreachable for hours. 

At first glance, it felt like just another tech hiccup. After all, outages happen. But the more I looked into what actually went wrong, the harder it became to ignore a bigger issue sitting underneath it all: how dangerously centralized today’s internet has become.

Cloudflare didn’t “break the internet” on purpose. But even its outage ended up revealing just how much of the internet depends on a handful of companies functioning perfectly at all times, and how fragile that arrangement really is.

When One Company Sneezes, Half the Internet Catches a Cold

Cloudflare isn’t an average household name, yet it plays a massive role in how the internet we all know and love operates. It provides your favorite websites with services like content delivery, DDoS protection, DNS resolution, and traffic routing for millions of websites worldwide. 

According to reporting by the Financial Times, a single Cloudflare outage in late 2025 affected platforms such as X (formerly Twitter), OpenAI services, numerous consumer and enterprise applications, and even digital government hubs (like the UK’s Financial Conduct Authority and MI5, the domestic intelligence agency) at the same time.

What struck me wasn’t just the scale of the disruption, but the cause. This wasn’t a cyberattack or a coordinated failure across multiple systems. The team behind Cloudflare later explained that the outage originated from an internal configuration change that triggered a cascade of failures inside its core infrastructure. In other words, one company made a mistake, and the ripple effects were felt globally.

That’s not a criticism of Cloudflare as much as it is a warning sign about centralization itself.

Centralization Looks Efficient, Until It Isn’t

I must admit, from a business perspective, centralization makes a lot of sense. Services like Cloudflare, Amazon Web Services, Google Cloud, and Microsoft Azure offer speed, scalability, and security that would be difficult or expensive for individual companies to replicate on their own. For startups, media outlets, and even governments, relying on large infrastructure providers is often the most practical option. But efficiency comes with trade-offs.

As multiple reports of the Cloudflare outage pointed out, centralization does create a single point of failure. Even organizations that host their servers across different regions worldwide can still go offline if they rely on the same intermediary layer for DNS or traffic routing. 

One breakdown upstream can effectively sever the connection between users and otherwise functional websites. As a result, you’re left staring at a blank browser screen.

This isn’t just a theoretical tirade. During the outage in November, many sites were technically “up,” but in reality, they were inaccessible because the centralized service connecting users to them had failed. Ultimately, the difference doesn’t matter to users staring at error messages.

The Real-World Costs of Centralized Failures

It’s easy to think of outages as temporary annoyances, but they come with real-life consequences for everyone involved.

For businesses, downtime on their website or service means tons of lost revenue. Studies cited by industry analysts estimate that large-scale internet outages can cost companies millions of dollars, depending on scale and sector. E-commerce platforms can’t sell. Customer support tools stop working. Internal systems grind to a halt.

For users, the impact is more personal but just as disruptive. Communication tools vanish. Navigation apps fail. Information you’ve always had at your fingertips becomes suddenly unavailable. During the Cloudflare outage, ironically enough, even services like DownDetector, which are designed explicitly to monitor outages, were unreachable, compounding people’s confusion and frustration.

What stood out to me during my research is how little choice users actually have in these situations. You can’t necessarily “opt out” of centralized infrastructure when it underpins the sites and services you rely on every day.

Centralization and the Illusion of Choice

We tend to think of the internet as inherently decentralized. There exist many sites, many voices, many options. But structurally, that’s becoming less true. Increasingly, a small number of infrastructure providers handle a significant portion of the traffic, granting them considerable influence over availability, performance, and access.

I’m not suggesting this power is usually abused. In most cases, it’s exercised quietly and automatically. But influence doesn’t have to be malicious to be consequential. When a handful of companies effectively act as gatekeepers for large portions of the web, freedom to choose becomes constrained by architecture rather than policy.

If your website depends on a single provider to stay reachable, your autonomy is limited by that dependency. If users can’t access information because one centralized layer fails, freedom of access becomes conditional. That feels at odds with how the internet was originally envisioned.

A Distributed Internet Was the Point

One thing that kept reemerging during research is that the internet was designed to be resilient. Early internet emphasized redundancy and distribution specifically so systems could “route around” failures. No single point of breakdown was supposed to bring everything down with it.

Yet modern internet infrastructure has gone in a completely opposite direction from its predecessors. Economic incentives reward consolidation. Convenience favors central platforms. Over time, resilience has taken a back seat to scale.

Academic research on decentralized systems suggests that architectural diversity (using multiple providers, distributed routing, and redundancy at different layers) can significantly reduce systemic risk. However, implementing those models requires more effort, more money, and greater technical complexity than many organizations are willing or able to undertake.

As a result, centralization persists, even when its risks are well documented.

What This Means for Internet Freedom Going Forward

I’m not arguing that centralized services should totally disappear overnight. That’s because they still solve real problems, and for many organizations, they’re indispensable. But the Cloudflare outage made one thing clear to me: we’ve accepted a level of structural fragility that should make us uncomfortable.

When large portions of the internet can go dark due to a single internal error at one company, we’re not just dealing with a technical inconvenience. We’re dealing with a concentration of power that affects access, expression, and economic activity on a global scale.

Online freedom isn’t only about content moderation or censorship. It’s also about whether people can reliably access information, communicate, and run businesses without being at the mercy of a few centralized choke points. Right now, that freedom feels more fragile than we like to admit.

Centralization Isn’t Inevitable; It’s a Choice

The takeaway here isn’t that Cloudflare is bad or that cloud infrastructure is inherently evil. The takeaway is that centralization is a design choice, and like any design choice, it has consequences.

Outages like this one are reminders that resilience, autonomy, and freedom online don’t come for free. They require intentional architectural decisions, diversified systems, and a willingness to prioritize long-term stability over short-term convenience.

I didn’t start researching this as an infrastructure expert. I came at it as someone trying to understand why the entire internet keeps failing in increasingly dramatic ways. What I found is a system that works well, until it suddenly doesn’t. And when it doesn’t, the costs are shared by everyone.
