How does the availability check work?

It requests the given URL from our server and shows the HTTP status code, load time, redirects and whether HTTPS is used. If a site is reachable for us but not for you, the issue is usually local (your connection, DNS or a regional block).

What do the HTTP status codes mean?

200 = OK, 301/302 = redirect, 401/403 = access denied, 404 = not found, 500 = server error. A load time under 500 ms is good, over 1500 ms is slow.

Is the check done from my device?

No – the request is made from our server in Germany, so it reflects reachability from the German internet, not your local connection.

Website Availability Check

The availability check tests whether a website or server is reachable from our server in Düsseldorf, Germany. It measures the HTTP status code, load time and checks whether HTTPS is used. This is useful to determine whether a website is generally down or only unavailable for you locally. Note: this test checks reachability from Germany – local outages in other regions may not be detected.
