Website Diagnostics
Website Status & Response Time Checker
Make a bounded request to a public website and inspect its status, redirect destination and server response time.
Check a website
The checker prefers HEAD and uses a small bounded GET only when HEAD is unsupported. It validates every redirect and never connects to a non-public target.
Understanding website status
HTTP status codes summarize how a server handled a request. Codes in the 200 range usually indicate success, 300-range codes redirect, 400-range codes describe client-side conditions and 500-range codes indicate a server-side failure.
What response time measures
This result measures the server-side diagnostic request, including DNS resolution, connection setup, TLS negotiation and followed redirects. It is not a browser performance score and can vary with load and network conditions.
Why redirects are rechecked
A public URL can redirect somewhere unsafe. WhatWebSees validates the scheme, hostname, port and all resolved addresses again before following each hop.
What this result means
The status family describes this one HTTP transaction: 2xx success, 3xx redirection, 4xx client/request conditions and 5xx server failures. Timing is a server-side snapshot, not page-load performance.
