A brief Cloudflare outage on Friday disrupted access to several major websites and online platforms, including Zoom, Canva and Fortnite, marking the second significant disruption linked to the company in recent weeks. The incident again drew attention to the heavy reliance on a small number of technology providers that support much of the global internet.
Reports of widespread issues began appearing early Friday, with Downdetector showing spikes in complaints across multiple services. Users said they were unable to load websites or encountered blank pages when trying to access platforms such as League of Legends, LinkedIn and Anthropic’s Claude chatbot.
Cloudflare acknowledged the disruption, describing it as “internal service degradation” affecting parts of its system. The company said the issue was tied to errors seen by customers running Workers scripts, as well as problems related to the Workers KV list API, which led to the appearance of empty pages.
“Cloudflare is investigating reports of a large number of empty pages when using the list API on a Workers KV namespace,” the company posted on its status page. It added that teams were analysing the cause and working to stabilise affected services. The outage lasted less than an hour before traffic began returning to normal.
The event echoed a similar episode in October, when Amazon Web Services experienced technical difficulties that disrupted access to data services for numerous companies in the United States. That outage led to cascading issues worldwide, affecting a broad segment of the internet.
The repeated incidents involving Cloudflare and AWS have renewed scrutiny over the concentration of global online traffic within a limited number of large content delivery networks (CDNs). These networks provide critical infrastructure by speeding up content delivery, reducing strain on servers and making websites more reliable — but they have also become central points of vulnerability.
Ryan Polk, director of policy at the Internet Society, said CDNs are vital for keeping the internet running smoothly, but their dominance means problems in one network can quickly ripple through the digital ecosystem.
“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,” Polk said.
Friday’s outage was short, but analysts say the incident highlights the broader risks facing the internet as dependence on centralised infrastructure intensifies. With global traffic continuing to rise, experts warn that even brief technical problems at major providers can cause significant disruption for businesses, public services and millions of everyday users.
