How this check works
We send one ordinary web request to the address from our server, follow any redirects, and report what came back: the HTTP status, how long each step took, where the redirects ended and which IP address answered. If the site ends up on plain HTTP, we also try HTTPS once to tell you whether it works.
It is a single check from one place at one moment. A site can be working for us and not for you, or the other way round, so the result also helps you work out where a problem is.
What the results mean
- Online: the server answered with a normal page or a redirect.
- Online: attention: the server answered, but with an error status such as 404, 403, 429 or 503. The site is reachable but that page isn't working normally, or it is blocking automated checks.
- Offline: the name doesn't exist, the connection was refused or timed out, or no secure connection could be made.
- Unable to determine: we couldn't get a reliable answer for a reason on our side, for example the site only has an IPv6 address.
If the site is down for you but online here
Try another network (for example mobile data instead of Wi-Fi), restart your router, clear your browser and DNS cache, or switch off VPNs and browser extensions. If the site is offline here too, the problem is most likely with the site or its hosting.
Frequently asked questions
The site says it is online but I can't open it. Why?
We check from our server, so the problem may be between you and the site: your internet connection, your DNS settings, a firewall or browser extension, or a regional outage. Try another network or device, clear your DNS cache, or wait a few minutes and check again.
Why does it say online when the site shows an error?
If the server answers at all, it is online, even when the answer is an error such as 404 or 503. We show those as Attention with the status code, because the site is reachable but not working normally for that page.
Does this check monitor the site over time?
No. Each check is a single snapshot from one location at the moment you run it. Results are saved for about a minute so repeated checks don't hit the site again. It isn't uptime monitoring, and we don't send alerts.
Why might a site block this check?
Some sites refuse automated requests, for example with a 403 or 429 status or a bot challenge. Our check identifies itself as ToolSiteCheck, so a site that blocks it may still work normally in a browser.
What does "Unable to determine" mean?
We couldn't get a reliable answer for a reason on our side, for example the site only has an IPv6 address and our server has no IPv6 connection, or the site's DNS servers didn't answer.
