Uptime Monitor

Run multi-attempt fetches to gauge latency, jitter, and real availability. Ideal before sending traffic to a new landing page or checking third-party reliability.

What is a Uptime Monitor?

A website uptime check confirms your site is reachable from outside your own network and measures how long it takes to respond. It is the fastest way to rule out a real outage when a client reports the site is down, or to sanity check a deploy from a neutral location. This tool runs a single on-demand check, it does not set up ongoing monitoring or alerts.

How to use this Uptime Monitor

  1. 1

    Enter the URL

    Paste the full address including https:// so the check hits the exact endpoint visitors use.

  2. 2

    Run the check

    The tool sends a request from an external server and waits for the response. Results come back in a few seconds.

  3. 3

    Read the status

    A 200 means the site loaded normally. A 301 or 302 is a redirect, 4xx points to a client or URL issue, and 5xx means the server failed.

  4. 4

    Check response time

    Under 500 ms is healthy for most marketing sites. Anything over 2 seconds is worth investigating, especially before a campaign push.

  5. 5

    Recheck after a fix

    Run the check again once your host, DNS, or deploy change is in place to confirm the site is back and responding cleanly.

Frequently asked questions

My site loads for me but this tool says it is down. Why?

Your browser may be hitting a cached copy, a CDN edge near you, or a server that only your IP can reach. An external check from a different network is closer to what most visitors actually experience.

Does this monitor my site continuously?

No. This is a single on-demand check. For continuous monitoring with alerts you want a dedicated service like UptimeRobot, Better Stack, or Pingdom.

What does the response time actually measure?

It is the time from sending the request to receiving the first byte of the response, including DNS lookup and TLS handshake. It does not include the time to render the full page in a browser.

Why does my site return a 403 or 401 on this check?

Some sites block requests that do not look like a normal browser, or require a login. The site may be up for real users even though the check fails. Try the URL of a public page rather than an admin or staging area.

Is the check free and is there a rate limit?

Yes, the check is free and does not require an account. There is a soft rate limit to prevent abuse, so space repeated checks a few seconds apart.
