Cloudflare, a company that supports much of the Internet’s infrastructure, experienced a major outage on Tuesday morning, causing disruptions to many websites and services globally. As of the time of publication, the company has not provided precise details on the disruption’s cause or a timeline for resolution.
Prominent websites such as X (formerly Twitter), OpenAI’s ChatGPT, and betting platform bet365 were among those affected. Users attempting to access these services encountered error messages, including warnings about potential security threats. Cloudflare attributed these messages to its systems’ malfunctioning rather than any actual security issues.
In a status update, Cloudflare stated, “We are seeing services recover, but customers may continue to observe higher-than-normal error rates as we continue remediation efforts.” Despite these assurances, many users reported ongoing problems with accessing affected websites.
Cloudflare’s tools, such as Access and WARP, were reportedly fixed earlier in the day, but the company acknowledged that other services were still being restored. The outage highlighted the company’s critical role in maintaining Internet functionality, as its systems are typically invisible to end-users.
Tracking website Down Detector continued to show issues with a variety of services, though it appeared that Cloudflare was making progress in mitigating the outage. The full impact of the disruption remains unclear, but it underscores the vulnerabilities inherent in centralized Internet infrastructure.
