An HTTP 200 from the final URL does not prove that the original user journey worked. A redirect may lead to a maintenance page, an unexpected hostname or a login endpoint. Check the registered target, redirect path and final response.

For HTTPS sites, inspect certificate hostname, validity and expiry alongside the latest completed HTTP check. A certificate can be valid while the application is unavailable, and a healthy response does not establish a vulnerability-free site.
Use the website status and SSL guide before escalating a change.
