The site I checked shows as "up" but I can't access it

Our check runs from our servers, not your device. If we can reach it but you can't, the issue is likely on your side. Check your DNS, browser, network, VPN, or firewall settings.

Why can't I check certain domains?

We block .onion domains and other potentially harmful extensions for security reasons.

Can I request a feature or report a bug?

Yes. Use the form above and include as much detail as possible so we can investigate.
