- Widespread global outage impacts major websites and services
- Root cause traced to Cloudflare’s configuration error, not cyber attack
- Highlights risks of dependence on centralised internet providers
A major internet outage on the morning of 18 November 2025 disrupted access to thousands of websites and digital services worldwide, underscoring the extent to which the modern web depends on a handful of infrastructure providers. The disruption was traced to Cloudflare, whose content delivery network and security services handle roughly a fifth of global web traffic.
The incident began shortly after 6.40am ET, when Cloudflare identified internal service degradation that rapidly spiralled into network-wide errors. Users trying to reach platforms including X, ChatGPT, Canva, Spotify, League of Legends and Grindr encountered pages labelled “Cloudflare: Error”, confirming that the fault lay in the company’s systems rather than with individual sites.
Cloudflare said the root cause was a problematic configuration file within its Bot Management system – a core tool used to identify and mitigate malicious traffic. An automatically generated file had unexpectedly grown too large, triggering instability across the network. The company stressed there was no evidence of a cyber attack.
The effects were felt across virtually every region hitting services that rely on Cloudflare to route traffic securely and efficiently. Public transport operators such as New Jersey Transit and France’s SNCF reported digital failures, while platforms including Coinbase and Moody’s saw temporary disruptions. The breadth of the outage highlighted how deeply Cloudflare’s infrastructure is woven into the functioning of the digital economy.
Crowdsourced reports on Downdetector peaked at nearly 5,000 during the worst period of disruption, although the site itself briefly went down due to its own reliance on Cloudflare. While Downdetector offers no diagnostic capability, the volume of complaints provided a snapshot of the outage’s scale.
The incident follows a string of major outages at cloud providers in recent months, including significant service interruptions at Microsoft Azure and Amazon Web Services that affected Snapchat, Reddit and other large platforms. Together they raise questions about system resilience as more essential services migrate to highly centralised cloud architectures.
By early afternoon ET, Cloudflare engineers had restored most services and were monitoring the network for further instability. The company’s CEO apologised for the disruption and released an initial post-mortem analysing the misconfiguration and the steps being taken to prevent a recurrence.
The outage has sharpened debate about the concentration of internet infrastructure in a small number of private hands. As digital systems become ever more central to daily life, commerce and emergency response, the reliability of a few backbone providers carries growing geopolitical and economic significance.
