Check whether a website is down for everyone or just you. Our free website down checker pings the URL from our servers in real time and reports HTTP status code, response time, and reachability — no signup, instant answer, unlimited probes.
Our global network of probes provides website availability data, with a strong emphasis on network conditions and accessibility within the United States.
We make a real HTTP request to the site from our own infrastructure and report exactly what happened: the status code, the time taken, and any redirects along the way. Because the request originates outside your network, your ISP and your browser cache, it isolates the variable everyone argues about during an outage — whether the site is genuinely down or only down for you. A 2xx or 3xx response means the server is alive and answering.
If we report the site up and you still cannot reach it, the fault is local: flush your DNS cache, try another network or mobile data, and check whether a VPN or corporate filter is intercepting the request. If we report it down, work up the stack — run a DNS lookup to confirm the domain still resolves to the right address, check the SSL certificate has not expired, then check your host's status page before opening a ticket.
| Code | Meaning | Action |
|---|---|---|
| 200 OK | Page loaded successfully | Site is up |
| 301 / 302 | Redirect | Follow the Location header |
| 403 | Forbidden | Access denied — check auth / firewall |
| 404 | Not found | URL does not exist on the server |
| 500 | Internal server error | App crashed — check server logs |
| 502 / 504 | Bad / Gateway timeout | Upstream is slow or unreachable |
| 503 | Service unavailable | Server overloaded or in maintenance |

An HTTP status code is a three-digit number returned by a web server in response to a browser's request. It indicates the status of the request. For example, 200 OK means success, 404 Not Found indicates the page is missing, and 503 Service Unavailable suggests temporary server issues. These codes are defined by the IETF in RFCs like RFC 9110.
This free website down checker gives an independent verdict on availability with a live status code and response time. Use it during incidents to confirm whether the problem is the server or your connection, then check DNS records and HTTP headers to find the root cause.
