About IsItDown

IsItDown answers a simple question fast: is a website down right now — or is it just you? Paste any website address and our checker contacts it directly from our server, then shows you a clear verdict along with the technical details.

What each check includes

• Up / Down / Error verdict — a clear, prominent result.
• Response time — total time plus a breakdown (DNS lookup, connection, first byte, TLS handshake).
• HTTP status — the status code with a plain-English explanation.
• Redirect chain — every hop the request took, with the final address.
• Content details — content type, server software and response size.
• SSL certificate — validity, issuer and expiry date for HTTPS sites.

One-click platform checks

Wondering about the big platforms? One tap checks TikTok, Facebook, Instagram, YouTube, X and WhatsApp instantly, and the live status board on the homepage keeps an eye on them for you.

Extra tools

The Tools section includes a DNS record lookup, an SSL expiry checker and a redirect checker that shows every hop between a link and its final address.

Is it free?

Yes. The checker is free to use with no account and no signup. The site is supported by advertising.

Accuracy note

Results reflect what our server sees at the moment of the check. A site can behave differently from your location or network, and some large platforms intentionally limit automated requests — in those cases we show exactly what the server returned so you can judge for yourself.
