About the Is It Up?
This tool checks whether a website is up or down right now. It makes an HTTP request from our server and reports a clear UP or DOWN verdict, the HTTP status code, the response time in milliseconds and the final URL after any redirects. It is the fast way to tell whether a site is genuinely offline or whether the problem is on your end.
The check runs once from a single location, so it answers "is the server responding" rather than replacing a multi-region uptime monitor. A 2xx or 3xx response counts as up; a failed connection, timeout or 5xx counts as down. Enter a bare domain or a full URL.
How to use it
- Enter a website domain or URL.
- Submit to make a single request from our server.
- Read the UP or DOWN verdict, status code and response time.
- If it is up for us but down for you, the issue is likely local or regional.
Examples
- Check whether a site is down for everyone or just you.
- Confirm a deployment is back online after maintenance.
- Measure a site's response time from our server.
Frequently asked questions
What counts as 'up'?
An HTTP response in the 2xx or 3xx range counts as up. Connection failures, timeouts and 5xx server errors count as down.
Is this a replacement for an uptime monitor?
No. It is a one-off check from a single location. For continuous, multi-region monitoring with alerts, use a dedicated uptime service.
Why does it say down when the site works for me?
The site may block automated requests, be slow to respond within the timeout, or have a regional issue. The tool reports what our server sees.
Can I check a site that requires login?
It checks the public HTTP response only. Pages behind authentication will typically return a redirect or an error status, which the tool reports as-is.
