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.
