November 18, 2025 – In a stark reminder of how fragile the modern internet can be, a major outage at Cloudflare, one of the world's largest content delivery networks (CDNs) and security providers, caused widespread disruptions across the web today. Starting around 11:48 UTC (early morning in the US), users reported an inability to access popular platforms, including X (formerly Twitter), OpenAI's ChatGPT, Spotify, Discord, and many others. The irony peaked when Downdetector, the go-to site for checking if services are down, itself became inaccessible for many users due to its reliance on Cloudflare.
Cloudflare confirmed the issue on its status page, describing it as an internal service degradation leading to widespread HTTP 500 errors (server-side failures), problems with its dashboard, and API outages. The company stated:
Cloudflare is aware of, and investigating an issue which impacts multiple customers: Widespread 500 errors, Cloudflare Dashboard and API also failing.
By early afternoon UTC, updates indicated that services were beginning to recover, though some elevated error rates persisted. Cloudflare identified the root cause and implemented fixes, with tools like Cloudflare Access and WARP (its VPN-like service) returning to normal. Temporary measures, such as disabling WARP in London, were used during remediation.
The outage affected a vast array of sites because Cloudflare acts as a reverse proxy for millions of websites: it handles traffic, caches content, provides DDoS protection, and secures connections. When it falters, the impact cascades, users saw error messages like "Internal server error on Cloudflare’s network" or were blocked by failed security challenges.
Peak reports on Downdetector (once it recovered) included:
This comes just weeks after a similar large-scale disruption at AWS, highlighting the risks of centralized internet infrastructure.
Cloudflare powers an estimated 20%+ of the web, offering free tiers that make it attractive for everything from personal blogs to major platforms. Its "proxy" mode hides origin servers behind Cloudflare's IP addresses, providing seamless DDoS mitigation and performance boosts. But as today's event showed, a single point of failure can ripple globally.
If recurring outages or dependency concerns have you rethinking Cloudflare, here are some strong alternatives for CDN, DDoS protection, WAF (web application firewall), and DNS services. These vary in pricing, features, and focus:
For free/low-cost DNS-only alternatives (if you just need fast resolution without proxying): Google Public DNS, Quad9, or Control D.
Many sites use multi-CDN strategies or failover setups to avoid total reliance on one provider – a lesson reinforced today.
While Cloudflare quickly mitigated the issue and services are largely restored as of late afternoon UTC, events like this underscore the internet's vulnerability to single-provider failures. Businesses and developers may want to audit dependencies and consider diversification.
Cloudflare has a strong track record overall, but for those seeking alternatives, the options above provide robust competition in performance, security, and cost. Stay tuned for Cloudflare's post-mortem report, which will likely detail the exact cause. In the meantime, the web is (mostly) back – refresh away!
