How a Single Cloudflare Bug Took Down Coinbase, Ledger, BitMEX and 20% of All Webpages

  • Cloudflare outage affected major crypto platforms and websites.
  • Centralized infrastructure creates single points of failure.
  • Industry leaders stress decentralization to preserve trustlessness.

A technical glitch at internet services giant Cloudflare triggered a major outage this week, temporarily taking offline roughly 20% of websites, including several prominent crypto platforms. The incident has reignited the debate over the crypto industry’s dependence on centralized infrastructure and the need for a more resilient, decentralized web.

Bot Detection Fault Behind Widespread Downtime

Cloudflare confirmed in a post-mortem statement that a “feature file” in its Bot Management System, designed to fend off cyberattacks, exceeded its normal size, causing a software failure. Initial fears of a large-scale Distributed Denial of Service (DDoS) attack were later dismissed. The outage affected major services like Coinbase, Blockchain.com, Ledger, BitMEX, Toncoin, Arbiscan, and DefiLlama, as well as non-crypto platforms including X and ChatGPT.

Centralized Systems Expose Single Points of Failure

The incident underscores the risks of relying heavily on centralized infrastructure. Cloudflare handles about 20% of global internet traffic and supports one-third of the top 10,000 websites. EthStorage, a company that offers Ethereum-based web hosting solutions, highlighted that outages at centralized providers such as AWS and Cloudflare demonstrate inherent single points of failure. Experts argue this vulnerability emphasizes the urgent need for decentralized internet solutions.

Industry Leaders Advocate for Decentralization

Ethereum co-founder Vitalik Buterin recently released a “Trustless Manifesto,” urging developers to prioritize decentralization over convenience. Buterin, alongside Ethereum Foundation researchers Yoav Weiss and Marissa Posner, warned that integrating centralized nodes or relayers introduces chokepoints, compromising trustlessness even when adoption benefits are tempting. The Cloudflare outage serves as a practical example of this principle, showing how centralized dependencies can disrupt the broader crypto ecosystem.

While Cloudflare quickly resolved the outage, the event is a stark reminder of the crypto sector’s reliance on centralized infrastructure. Industry leaders and developers are increasingly advocating for decentralized architectures to safeguard trustless principles and ensure platforms remain resilient during similar technical failures.
