Cloudflare Outage Triggers Global Internet Meltdown — X, ChatGPT, Claude & Perplexity Go Down
A massive global outage shook the internet on Tuesday after Cloudflare, one of the world’s largest internet infrastructure providers, suffered a major internal incident. The disruption briefly took down or degraded access to major platforms including X (Twitter), ChatGPT, Anthropic’s Claude, Perplexity AI, Canva, Spotify, and several gaming and cloud services.
What Went Wrong
Cloudflare confirmed that the issue began around 11:20 UTC when an unexpected surge of unusual traffic hit one of its core services. This caused widespread 500 Internal Server Errors across websites and apps that rely on Cloudflare’s CDN, DNS, and security layers.
Because Cloudflare handles roughly 20% of all global web traffic, the outage quickly cascaded across multiple regions, overwhelming popular platforms and user-facing services.
Who Was Affected
The outage impacted millions of users attempting to access:
X/Twitter
ChatGPT
Claude
Perplexity AI
Canva
Google Cloud–linked apps
Gaming platforms like Riot Games
Monitoring tools like Downdetector (ironically also hit)
Many users reported challenges like sites refusing to load, login failures, error pages, or Cloudflare-related security prompts failing to verify.

Restoration & Current Status
By early evening (IST), Cloudflare reported that the incident had been contained, with services gradually returning to normal. However, some platforms continued experiencing residual slowdowns as systems stabilized.
Why This Matters
This outage highlights the fragile dependency the global internet has on a few backbone providers. When a single CDN or DNS network experiences an internal failure, even the biggest AI platforms and social networks go down simultaneously.
For businesses, the event underscores the need for:
Multi-provider redundancy
Failover strategies
Real-time dependency monitoring
Tech Byte Daily Verdict
While services are back online, the November 18 outage will be remembered as one of the most disruptive internet events of 2025 — a wake-up call on how critical Cloudflare is to the modern digital world.
