Cloudflare DOWN: Why X (Twitter), OpenAI, and the Internet Went Offline
Did you wake up to half the internet not working? On November 18, 2025, major platforms like X, OpenAI, Canva, Letterboxd, and popular games suddenly went down because Cloudflare, one of the internet’s main infrastructure providers, experienced a major outage.
This video explains what went wrong, why your favourite pages showed error messages, and how a single Cloudflare failure caused a chain reaction across the web. Even tools like DownDetector and Cloudflare’s own login system, Turnstile, went offline.
We also look at why outages like this keep happening, and how our reliance on a few big providers makes the whole internet more fragile.
What you’ll learn:
• What triggered the Cloudflare outage
• Which major sites were affected
• Why verification and logins failed everywhere
• How one provider’s issue can take down huge parts of the internet.
