Four checks answer four different questions
HTTPS/SSL checks whether secure access is working. Redirect tracing shows where a URL sends visitors. HTTP status reveals the initial server response. Response time measures how quickly a server answers from a Cloudflare edge.
Start with availability and HTTPS
Use Website Down Checker and the SSL Checker. If HTTPS fails, browsers may warn users or refuse secure connections.
Trace routing problems
Use the Redirect Checker when old URLs, www/non-www, HTTP/HTTPS or marketing links do not end where expected. A long chain adds complexity and can make debugging harder.
Inspect the response itself
The HTTP Status Checker shows the initial status. Then use the Website Response Time Test for several server-side timing samples.
