We test your connection and the website at the same time — your line from your browser, the site from Cloudflare's edge — and settle it in 10 seconds.
Type a site that's giving you trouble — or tap one of the popular ones above to see it in action.
We measure your own connection from your browser while a Cloudflare edge server — not your machine — checks how fast the site responds.
In about 10 seconds you know which side is to blame: it's you, it's the site, it's both, or all clear.

Test both at the same time. itsnotyou measures your own connection from your browser and, separately, asks a Cloudflare edge server how fast the website responds. If the site is slow or down from the edge too, it's the site — not you. If the edge reaches it fine but your line is struggling, the problem is on your end. You get one verdict in about 10 seconds, with no login.
If only you can't reach a site, it's usually local — your Wi-Fi, router, or ISP. itsnotyou confirms this by checking the website from Cloudflare's network at the same moment it measures your line: when the edge loads the site quickly but your connection is slow, the bottleneck is your Wi-Fi or connection, not the site.
A site that is down for everyone means its own servers are not responding — which itsnotyou detects by probing the site from Cloudflare's edge, independently of your connection. If the edge cannot reach it either, it is down for everyone; if the edge reaches it but you cannot, it is just you.
No. itsnotyou has no login, sets no tracking cookies, and stores nothing about you or which sites you test. The test runs in your browser and against Cloudflare's edge, and the verdict is shown once, not saved.
