How do I check if Cloudflare is having issues?

This page checks Cloudflare availability in real time. You can also monitor Cloudflare continuously with Visual Sentinel, get instant alerts via email, Slack, Discord, or WhatsApp when Cloudflare goes down.

How can I get alerted when Cloudflare goes down?

Set up a free monitor for cloudflare.com on Visual Sentinel. You will get alerts within 60 seconds via your choice of 10 notification channels including email, WhatsApp, Slack, Discord, and Telegram.

Where is the official Cloudflare status page?

The official Cloudflare status page is at https://www.cloudflarestatus.com/. However, official status pages often lag behind real outages. Visual Sentinel detects Cloudflare issues independently with 60-second checks from multiple global regions.

What does "Cloudflare Error 521" mean during an outage?

Error 521 means Cloudflare cannot reach your origin server. During Cloudflare-side outages, this can happen even when your origin is healthy because edge-to-origin routes are affected. During origin outages, your server itself is down. Check your origin directly (bypass Cloudflare) to distinguish.

Does a Cloudflare outage break sites that only use Cloudflare DNS?

Yes. If the authoritative DNS for a domain is hosted on Cloudflare and the DNS service is affected, resolvers cannot look up the domain. Visitors see NXDOMAIN or timeouts even though the origin server is fine. Backup DNS or secondary authoritative providers mitigate this.

about this service

About Cloudflare

Cloudflare is a core internet backbone provider, running a CDN, DDoS protection, DNS resolution, Workers (edge compute), R2 (S3-compatible object storage), Pages (JAMstack hosting), Zero Trust (SSE/SASE), and the 1.1.1.1 public resolver. Because so much of the web proxies through Cloudflare, an outage can feel like the whole internet is down. Incidents are scoped per data center (Cloudflare has hundreds of POPs globally) or per product. Customers frequently see "Error 1020" or "Error 521" pages during partial outages where Cloudflare cannot reach origin servers. BGP-related incidents at Cloudflare have taken down unrelated sites that just happen to use Cloudflare DNS.

The official Cloudflare status page is at www.cloudflarestatus.com. However, official status pages are often updated manually and can lag behind real outages by minutes or hours. Independent monitoring catches issues faster.
