If your favorite websites or critical online tools mysteriously stopped working today, you weren't alone. From social media feeds failing to load to crucial work applications throwing "500 Internal Server Errors," a significant chunk of the internet experienced a frustrating slowdown or complete halt. The culprit? A major global outage at Cloudflare, one of the foundational companies that keeps the internet running smoothly.
Imagine the internet as a vast, interconnected city. Cloudflare acts like a crucial public utility – think of them as the company managing the city's main power grid and traffic control systems. They provide services like:
When a company of Cloudflare's magnitude experiences issues, the ripple effect is immediate and widespread. Starting around 11:45 UTC today (November 18, 2025), reports flooded in from users across the globe. Websites that rely on Cloudflare for any of their critical services – and there are millions of them, including giants like OpenAI (ChatGPT), Canva, and X (formerly Twitter) – suddenly became inaccessible or highly unstable.
The screenshot below from Cloudflare's own status page illustrates the severity of the situation, showing major outages and re-routed traffic, indicating a scramble to restore services.

For many of us, an internet outage is simply an annoyance. We can't watch our favorite show, send an important email, or check social media. But for businesses, this type of disruption has much graver implications:
This event serves as a stark reminder of how deeply reliant our modern world is on a few key pieces of digital infrastructure. When one of these pillars falters, the effects cascade across industries and continents.
Cloudflare's engineers worked quickly to identify and mitigate the issue. According to their status updates, services began to recover gradually, with traffic being re-routed to bypass affected areas. While the immediate crisis seems to be stabilizing, some users may still experience residual instability or higher error rates as the network fully recalibrates.
The full "Root Cause Analysis" (RCA) – the detailed explanation of what went wrong and how it will be prevented in the future – will likely follow in the coming days. These reports are crucial for tech companies and the wider internet community to learn from such incidents.
For the average internet user, today was a lesson in digital patience. For businesses, it's a powerful call to action:
As the internet continues to evolve, so too must our understanding and preparation for its inevitable bumps in the road. Today's Cloudflare outage was a significant bump, reminding us all of the complex, interconnected, and sometimes fragile nature of our digital world.
