Yesterday (November 18, 2025), Cloudflare one of the biggest internet outages in history occurred when Cloudfire experienced a catastrophic failure. Cloudfire takes care of almost a fifth of the internet, so when they went down, thousands of services, including social media giant X (formerly Twitter), AI ChatGPT, and even fast-food delivery apps like McDonald’s, went down. Users around the world reported ‘error’ and ‘loading’ screens at around 6:30 AM ET. Peak outages reached about 11,000, and technicians had the situation resolved by the ‘mid-afternoon’ but not before people began discussing issues the internet and society face.
What is Cloudflare?
Cloudflare is one of the biggest companies that keeps the internet fast and safe.
- Acts like a super-fast shield in front of millions of websites
- Blocks hackers, spam, and DDoS attacks
- Speeds up loading times by caching content around the world
- Used by ≈20–25% of all websites (including big names like X, Discord, Shopify stores, news sites, and even small blogs) When Cloudflare has a problem, huge chunks of the internet can go offline at the same time.
What Caused the Outage?
A safety file that automatically blocks bad bots grew too large → the file crashed Cloudflare’s main routing system.
- A safety file that blocks bad bots got way too big
- That giant file crashed Cloudflare’s main system
- No one hacked them — it was their own automatic system that broke
- Started around lunch time in Europe / early morning in USA
- Fully fixed by late afternoon

Challenges When Cloudflare Blocks You (How to Unblock)
Cloudflare can error out sometimes and think you’re a bot by showing `Error 1020` or endless `Checking your browser` screens. Here are some easy suggestions that can help:
- Go incognito or clear your cache and cookies.
- Change or disable your VPN.
- Switch your network connection from Wi-Fi to mobile data or vice versa.
- Wait a few minutes, as any blocks will usually expire on their own.
- Consider disabling browser extensions, especially any that are about ad-blocking.
- If you find yourself in a restricted country, you can use a reliable VPN to connect to an allowed location.
Final Takeaway
Yesterday was a big but accidental outage. Today everything is fixed and running normally. Cloudflare is back to protecting and speeding up the internet as usual. If you like article like this make sure to also read: China–Japan Travel Warning: Latest Safety Update
