About itsnotyou
Every internet user has had the same argument with themselves. A page won't load, a video keeps buffering, an app spins forever — and you can't tell whether the problem is your own connection or the website itself. It matters, because the two need completely different responses: one you can fix in a minute, the other you can only wait out.
itsnotyou exists to end that argument in about ten seconds. You type in a website, and we run two independent checks at the same moment, then hand you a single plain-language verdict: it's not you, it's you, it's both, or all clear.
How the measurement actually works
The whole idea rests on measuring both ends of the connection simultaneously and comparing them. A slow page is a chain: your device and network on one end, the website's servers on the other. To find the weak link, you have to test both — separately — and see which one is actually struggling.
- Your side is measured inside your own browser. We time the round-trip latency to our server and how quickly a small test file downloads, so the reading reflects the real connection you're sitting on right now — your Wi-Fi, your router, your ISP.
- The website's side is measured from a completely different vantage point: a server on Cloudflare's global edge network asks the site how fast it responds. Because that check doesn't touch your machine or your network, it shows whether the site is healthy for the outside world, independent of you.
Put the two readings side by side and the answer falls out. If the edge reaches the site quickly but your line is slow, the bottleneck is on your end. If the site is slow or unreachable from the edge too, it isn't you — it's them. It's a simple idea, executed carefully, and it's more reliable than refreshing the page and guessing.

The live status pages
Alongside the test, we keep always-on status pages for a curated list of popular sites and services — streaming, social, gaming, banking, public services, AI tools and more. Each one is probed continuously from our monitoring servers, shows whether the site is up, slow or down right now, and plots a 24-hour history of its response time. They answer the question "is it down for everyone, or just me?" without you having to run anything.
Independent, free, and privacy-first
itsnotyou is not affiliated with, endorsed by, or sponsored by any of the websites it tests or monitors. The measurements are our own, taken from a neutral position, and we call them as we see them.
The service is free to use, needs no account, and is deliberately built to know as little about you as possible: the test runs in your browser, we set no tracking cookies of our own, and we don't store a record of who tested what. The full detail is in our privacy policy. We keep the lights on through unobtrusive advertising and the occasional relevant affiliate link — never at the expense of giving you a straight answer first.
Who's behind it
itsnotyou is built and run by a small, independent group of internet and networking nerds — the kind of people friends and family already call when the Wi-Fi acts up. We got tired of never knowing whether the problem was us or the site, so we built the tool we wanted. Questions, corrections, feedback, or a request from a site owner?
