Do Cloudflare’s Two Outages Expose the Internet’s Fragility?

Not once but twice in two weeks, Cloudflare has gone down – not only sending shockwaves across the Internet but exposing just how much of the web relies on a handful of infrastructure providers. 

From enterprise portals and fintech apps to small e‑commerce sites, the ripple effect of each outage has been immediate and widespread.

Cloud and security giant Cloudflare – which underpins a vast portion of the Internet through its content delivery, DNS and edge security network – faced performance and connectivity issues again last week following a similar disruption just days earlier. 

For businesses and developers dependent on Cloudflare’s services, this disruption is a reminder of how fragile the digital ecosystem can be.

Warning signs of Internet centralisation

According to Richard Ford, CTO at Integrity360, the events have laid bare the structural vulnerabilities built into today’s online infrastructure.

“As the Internet has grown more complex, a handful of infrastructure providers end up holding unexpectedly large power over its functioning,” he explains. “Cloudflare sits at the heart of that, providing CDN, proxying, routing, DNS and caching so that websites can stay fast, secure and resilient under load.

“When a provider like this fails, whether due to internal error, configuration change or external attack, the ripple effects hit far more than just a few sites. What feels like one outage to a user is actually a systemic failure affecting traffic flows across many unrelated organisations.

“For businesses, this is a wake‑up call. Relying entirely on a single provider for critical infrastructure is a fragile strategy. 

“Companies should be thinking now about redundancies – multi‑CDN configurations, fallback hosting or hybrid cloud setups – so one failure doesn’t take everything down.”

Has this concentration problem been years in the making?

Ryan Polk, Director of Policy at the Internet Society, points to decades of market consolidation among the few players delivering the majority of global Internet traffic as a central cause for concern.

AWS, another dominant player in the space, similarly experienced a string of disruption in October thanks to an internal automation fault in its US-East-1 region triggered a cascade of DNS failures. Thousands of businesses and millions of Internet users were affected.

This, Ryan says, emphasises “how heavily the Internet depends on a small number of major CDNs”. 

The Internet Society’s Pulse platform says that market concentration among CDNs has steadily increased over the past five years.

“CDNs offer clear advantages – they improve reliability, reduce latency and lower transit demand,” he shares. “However, when too much Internet traffic is concentrated within a few providers, these networks can become single points of failure that disrupt access to large parts of the Internet.

“Organisations should assess the resilience of the services they rely on and examine their supply chains. Which systems and providers are critical to their operations? Where do single points of failure exist? 

“Companies should explore ways to diversify – such as using multiple cloud, CDN or authentication providers – to reduce risk and improve overall resilience.”

From chokepoints to distributed pathways

For Austin Federa, Co‑Founder of DoubleZero, the latest round of Cloudflare disruption highlights a deeper design flaw at the heart of the modern Internet, calling it “another reminder of what happens when critical internet functions, like DNS, CDN, WAF and edge compute, are funnelled through a single global chokepoint”. 

He adds: “When that one layer stumbles, everything stacked on top of it goes dark. And with the scale of this disruption, it’s clear we’re now facing a broader structural issue, not just another isolated incident.”

For Austin, these cascading failures hit emerging technologies such as AI and blockchain particularly hard. 

“AI and blockchain systems feel this even more acutely because they rely on thousands of machines staying perfectly synchronised,” he adds. 

“These workloads need architectures with fundamentally different failure modes such as distributed backbones with no central chokepoint, user-controlled routing and instant fallback paths that keep systems operating even when a major provider goes down.

“Outages will still occur, but their blast radius can be contained. Until real-time systems move off single-vendor edges and onto distributed pathways, disruptions of this size will keep surfacing and each one will show how urgently the internet needs a different foundation.”
