- Cloudflare errors 521–523 mean the site's own server is offline, even though Cloudflare still answers.

Frequently Asked Questions
Quick answers about Is Website Down Checker.
Enter the address and click Check. We test the site from our own server, so if it shows UP here but doesn't open for you, the problem is your connection, browser or network.
Common reasons are a DNS cache problem, a VPN or proxy, a browser extension, your internet provider blocking the site, or an old cached page. Try another network or browser.
The domain name could not be found. It may be misspelled, the domain may have expired, or its DNS settings are broken.
The server did not answer in time. It may be overloaded, offline, or blocking connections.
No. The server is online but refused our automated check, often because of bot protection like Cloudflare. It will usually still open for normal visitors.
Yes. Paste the full page link, for example https://example.com/blog/post.
No. We only keep a short-lived cached copy of the result (so repeated checks are fast), and we never sell or share it.
