URL diagnostics

Website Checker

Run a full website report with one combined verdict plus Russia and Finland results for DNS timing, TCP connect time, TLS handshake time, TTFB, redirect chain, final URL, response headers, and resolved IP addresses.

Start here when you need to know whether a public website responds cleanly in Russia, Finland, or both, and where the request path slows down or fails.

Website & SSL

Free public tool. No account required.

Summary

This tool runs in Russia and Finland and returns one combined report from the diagnostics backend. Differences can come from routing, resolver answers, TLS presentation, CDN edge selection, or filtering policy.

Request path and redirect behavior

You get the normalized URL, redirect chain, final URL, HTTP status, and the address the final hop resolved to.

Timing breakdown

The backend captures DNS resolve time, TCP connect time, TLS handshake time for HTTPS, time to first byte, and overall time for the final hop.

HTTPS and platform hints

If the target ends on HTTPS, the report includes certificate details and explainable hosting or CMS markers when the response exposes them.

Website URL

Website Checker

Ready

Paste a full URL or a plain domain. The backend normalizes safe public targets and blocks localhost, private ranges, and internal hostnames.

How to use it

01

Paste the public URL you want to inspect and run the check.

02

Look at the final status and explanation first, then open the timings and redirect chain sections.

03

If the result points to TLS, DNS, or hosting issues, jump directly to the related tool pages linked below.

How to read the result

An HTTP warning is not a network failure

An HTTP 403 or 503 means the request reached the server but the response was not usable. DNS, timeout, or TLS failures happen earlier in the path.

Resolved addresses matter

A site can move between IPv4 and IPv6, serve different edges, or present different behaviors depending on the address family the server picked.

Screenshot support is optional

If this deployment does not have safe screenshot capture enabled, the report says so instead of pretending to have a screenshot.

Website Checker FAQ

Why can a site be online but still show a warning?

Because the site may respond with an HTTP error like 403, 429, or 503. That still proves the server answered, but not that the page is usable.

What does TTFB represent here?

It is the time from the start of the HTTP request to the first response byte on the final hop, after the server completed DNS and connection work.

Can redirects hide a problem?

Yes. One hop might be fast and healthy while the final destination is slow, blocked, or mistrusted. That is why the chain is shown explicitly.
