Why might a site work in my browser but show a problem here?

This check runs from SiteIndex's server, which avoids browser-only network issues, so it reflects general public reachability rather than your personal connection.

Is the website down for everyone or just me?

This request checks reachability from SiteIndex's server. If it succeeds here but fails on your device, compare another network and check local DNS, VPN, firewall, or browser settings.

Does this provide continuous uptime monitoring?

No. It is a one-time check when you run it, not a scheduled monitor or alerting service.

How is this different from HTTP Status Checker?

Website Down Checker gives a quick reachability and UP/DOWN summary; HTTP Status Checker focuses on the response code, redirect chain, and headers.

Is My Website Down? Check Any Site

Check if a website is down from SiteIndex's server and review the response status and redirect chain.

Guide

No account required

Check website status

Review the response code, redirect chain, and headers for a public URL.

Website URL

Enter a public URL above to see its HTTP response.

Repeat timing sample & raw headers

Run three back-to-back checks to see response-time variance, and review the complete raw header set.

How to use it

Enter the public website URL you want to check.
Run the request and read the UP or DOWN result and HTTP status.
Review redirects and response timing to understand what happened.
Re-check after a fix or compare with your local browser if results differ.

What is Is My Website Down??

Test if a site is reachable and quickly review the response status and timing.

How it works

SiteIndex's server checks the site directly (avoiding browser CORS limits) and reports the status code, response time, and full redirect chain. The Advanced panel adds repeat timing samples to help distinguish a one-off slowdown from a consistent problem.

Common uses

Check whether a site is down for everyone or just for you.
Confirm a site recovered after an outage or deployment.
Spot a slow or unstable response before customers report it.

Limitations

Results depend on the browser, network, input, and external service involved.
