A massive spike in unusual traffic has triggered a global infrastructure outage, knocking major platforms including X, ChatGPT and Spotify offline whilst disrupting services for tens of thousands of users.
Users attempting to access affected sites encountered security error messages demanding they “unblock challenges.cloudflare.com” as the infrastructure firm scrambled to restore service, reports The Verge.
The outage struck shortly before 7:00 a.m. ET, affecting the content delivery network and security tools that underpin vast swathes of the internet. The disruption was severe enough to take down Downdetector, the website users typically rely on to track such outages, along with services ranging from Uber to the digital outlets of Politico and Axios.
Cloudflare spokesperson Jackie Dutton confirmed the company observed a traffic surge beginning at 6:20 a.m. ET.
“We do not yet know the cause of the spike in unusual traffic. We are all hands on deck to make sure all traffic is served without errors,” said Dutton.
Swift reactions
The company’s engineering team was forced to disable WARP access in London to mitigate the issue. Market reaction was swift, with Cloudflare shares dropping 4.7 per cent in premarket trading following the incident, which echoes a major Amazon Web Services crash that disrupted services for millions of users last month.
The service disruption occurred less than 24 hours after the company announced it agreed to acquire Replicate, an AI platform designed to simplify model deployment for developers.
The deal aims to accelerate the vision for Cloudflare Workers by allowing developers to access 50,000 production-ready AI models with a single line of code. The San Francisco-based company plans to integrate Replicate’s technology to abstract away the hardware and infrastructure complexities typically associated with running scalable AI applications.
“With Replicate, developers will be able to discover any model they want from one of the industry’s largest catalogs, deploy it instantly on Cloudflare’s global network, and build an entire full-stack application in one place,” said Matthew Prince, co-founder and CEO of Cloudflare.
