A major Cloudflare outage caused widespread disruption on the internet, temporarily taking down numerous popular websites around the globe. Among the affected platforms were X (formerly Twitter), Substack, Canva, and many other services.

Notably, even Down Detector, the well-known platform that tracks website outages, went offline — highlighting the scale of the problem, as it relies on Cloudflare’s infrastructure.

Interestingly, some websites that were impacted by last month’s massive blackout remained unaffected this time. This is likely because they have since reduced their dependence on Cloudflare services. ChatGPT was among these platforms and continued operating normally.

Thousands of users attempting to visit popular websites were greeted with the message “500 internal server error” instead of the expected content, while access to some sites was completely blocked for several minutes.

This incident comes just two and a half weeks after Cloudflare’s previous major outage, which had taken a significant portion of the internet offline for hours.

Cloudflare provides essential internet infrastructure services to thousands of websites worldwide, acting as an intermediary that ensures websites stay online even under high traffic conditions.

However, this heavy dependence means that any malfunction at Cloudflare can instantly affect multiple platforms, triggering a chain reaction of online outages — as occurred in this latest disruption.
