UpCheck

Free website status checker

Is your website up?

Enter any public URL. UpCheck sends a real request from Cloudflare's network and shows the status, response time, and connection details. No account. No stored history.

A live HTTP check. Results are never simulated.

Try
Live status A real HTTP response
Real timing Measured, not estimated
Server details IP, location, redirects

How it works

Three steps. One real request.

UpCheck doesn't show a canned "online" badge. The check is made live when you press the button, and the numbers come from that request.

  1. 01

    Paste a URL

    Any public http or https address works. If you leave off https://, UpCheck adds it for you.

  2. 02

    We send a real request

    The request runs from Cloudflare's network. We record the actual HTTP status, redirects, DNS lookup, and timing. Nothing is simulated.

  3. 03

    Read the facts

    See whether the site answered, how long the first byte took, which IP it resolved to, and the approximate location of that IP.

Reading the result

What each verdict means.

UpCheck separates a healthy answer from a reachable server that returned an error.

Up

The final response was a 2xx, or a 3xx that led to a valid final response. The site answered from Cloudflare's network.

Issue

The server answered with a 4xx or 5xx error, or the redirect chain could not be followed. The site is reachable, but not healthy.

No response

Nothing came back within 12 seconds, or the domain could not be resolved. This is a result from our network, not a global outage verdict.

FAQ

Questions, answered.

Is UpCheck free?

Yes. There is no account, no payment, and no stored check history. A fair-use rate limit keeps the service available for everyone.

Does a failed check mean a site is down for everyone?

Not necessarily. UpCheck reports whether Cloudflare's network received a response. A regional outage, a local network issue, or bot protection can produce a different result from your browser.

What does the response time measure?

Response time runs from the start of the first HTTP request, through any redirects, to the first byte of the final response. The DNS lookup is measured separately.

Why do some sites show an error here but load normally in my browser?

Some sites block automated requests, require a login or JavaScript, or rate-limit unfamiliar traffic. UpCheck reports the real response it receives; it does not simulate a browser session.

What happens to the URLs I check?

UpCheck has no accounts and no database, and it does not store your check history. The URL is used for the live request and then discarded. Cloudflare and the lookup providers process requests as described in the privacy policy.

Can I check localhost or a private network address?

No. Local and private addresses are blocked so the tool cannot be used to probe internal systems.

How accurate is the server location?

IP geolocation is approximate. It usually points to the hosting provider or CDN edge, not necessarily the company's office.
