Is your website reachable or just down?
Check whether a website is accessible from the Seitenreport server. You get the HTTP status, the forwarding destination and a classification of possible access blocks or server errors.

A second perspective on accessibility
If a website does not load with you, the cause may be in the local network, DNS, browser or on the web server. A query from another server helps with the delimitation. This tool retrieves the entered URL via HTTP or HTTPS and tracks up to two forwards. The measurement is done once from one location, not via a worldwide test network.
Differentiate response code and failure
HTTP 200 means that the server has successfully answered the request; an error message in the page content is still possible. 404 affects the specific URL and does not prove a failure of the entire domain. 500, 502 or 503 speak for a server-side interference or an upstream service. 403 and 429 can specifically block the check server while visitors continue to reach the website.
Then you can limit a disturbance.
First, compare the homepage with the affected underside. Then check DNS resolution and TLS certificate. When forwarding, check whether the displayed destination is correct. If the server answers here, but not in your browser, another network and browser network analysis will help. Both do not answer, check hosting status and server logs.
Snapshot instead of availability statistics
The specified duration relates to the last HTTP retrieval. It does not include a complete representation with images, CSS and JavaScript. A single successful call results in no uptime of 100 percent, a single error no worldwide failure. For recurring observation, use monitoring; for error pages with status 200, the Soft 404 Checker.
Example of classification
HTTP 429 means “too many requests”. The result shows a response from the server and an access restriction, not automatically a complete failure of the website.
Frequent questions
Does the tool test from several countries?
No. It is a single measurement from the Seitenreport test server.
Is the response time equal to the loading time?
No. The HTTP retrieval is measured, not the presentation in the browser with all resources.
Will the website be automatically monitored afterwards?
No. For a new snapshot, you need to check again.
