Is Cloudflare down?
Live status for Cloudflare (https://cloudflare.com)
About Cloudflare outages
Cloudflare fronts a huge share of the web with CDN, DNS, and security services — which is why a single Cloudflare incident can make thousands of unrelated websites show 5xx errors simultaneously.
Cloudflare publishes official incident updates at its status page — worth checking alongside our live test above.
Cloudflare FAQ
Why are many different websites down at the same time?
When lots of unrelated sites fail together with 500-class errors, a shared infrastructure provider like Cloudflare is the usual suspect. Cloudflare error pages name themselves (error 500/502/521 with a Cloudflare banner), which confirms where the failure lives.
What does Cloudflare error 521 mean?
Error 521 means Cloudflare is up but the website’s own origin server refused the connection — the site behind Cloudflare is down, not Cloudflare. It is a useful distinction: 521 points at the site operator, while widespread 500s point at Cloudflare itself.
Is Cloudflare down for everyone or just me?
We test Cloudflare (https://cloudflare.com) live from our own servers. If our check succeeds but you still can't connect, the outage is probably local to you — try another network or device, clear your cache, or check Cloudflare's official status channels.
