About itsnotyou
itsnotyou.site answers one question: when a website feels slow, is it your internet or the site itself? You enter a website; we measure your own connection from your browser and the site's response time from a neutral server, at the same time, and give you one verdict in about ten seconds. It's free, needs no login, and sets no cookies of its own. There's more on how that works in our help articles.
To keep the status pages (like is ChatGPT down?) current, we also run a small monitoring bot. If you run a website and you're reading this because you saw it in your logs, this page is for you.
The itsnotyou-probe bot
Our monitor identifies itself with this User-Agent:
Mozilla/5.0 (compatible; itsnotyou-probe/1.0; +https://itsnotyou.site/about)
It is deliberately one of the lightest possible visitors. Here is exactly what it does:
| What | Detail |
|---|---|
| How often | Once every 2 minutes per site — the same cadence as a standard uptime monitor. One extra retry only if a check fails. |
| What it requests | A single request to your homepage, then it reads only the response headers and discards the body — it never downloads the page. |
| What it measures | Whether the site responded, the status code, and time-to-first-byte. That's it. |
| What it stores | Up / slow / down and a response time. No page content, no scraping, no copying, no indexing of your site. |
| Where it comes from | Our own monitoring servers (not a visitor's browser). |
At one request every two minutes with no page download, the load on your server is negligible — a few kilobytes of headers, roughly 720 times a day. We monitor only well-known public services people commonly ask about; we do not crawl or discover new sites.
For site owners: opting out
If you'd prefer we didn't check your site, just ask — no questions, no forms. Email cw.nett.post@gmail.com with your domain and we will:
- remove it from the monitoring roster, so the every-2-minutes checks stop, and
- block it from on-demand tests, so our tool won't probe it even if a visitor types it in.
We action removal requests quickly. If you're seeing anything from this User-Agent that doesn't match the description above, please tell us at the same address — we want to know.
