Many popular websites and apps, including ChatGPT, Twitter, Spotify, Canva, and Perplexity, went down on Monday due to a technical problem at Cloudflare, a company that helps deliver internet content safely. Users trying to access these sites saw a message saying: “Please unblock challenges.cloudflare.com to proceed.”
The issue started early in the morning and was caused by a glitch in Cloudflare’s system that checks for unsafe traffic. Instead of blocking threats, the bug accidentally stopped normal users from entering websites. The outage affected people across the world, causing confusion and frustration.
Cloudflare confirmed it was a technical problem, not a hacking attack. The company quickly fixed the issue, and most websites were back online by the evening, though some users experienced brief interruptions.
Tech experts say this shows how much the internet depends on a few major companies. When one service goes down, it can impact many websites and millions of users at once.
Cloudflare said it is reviewing its systems to prevent similar problems in the future. Most services are now running normally, and users can access the affected websites again.
