Check whether a website is up or down for everyone, not just you. Enter any URL to instantly test the site's HTTP status code, server response time, and overall availability — from our servers, not your local connection. No sign-up required and completely free.
When you submit a URL, our server sends a direct HTTP request to the target website and measures its response. The result includes the HTTP status code (200 OK, 403 Forbidden, 503 Service Unavailable, etc.), the server's response time in milliseconds, and the content type returned. Because the check originates from an external server, it accurately reflects whether the site is globally reachable — not just visible from your cached browser session.
HTTP 200 means the website is up and responding normally. HTTP 301 or 302 indicates the site is up but redirecting to another URL. HTTP 403 means the server is reachable but is refusing automated access (common with Reddit, Facebook, and Cloudflare-protected sites — the site is usually up for regular users). HTTP 503 means the server is temporarily overloaded or undergoing maintenance. A complete timeout or connection failure suggests the server is down or the domain has a DNS problem.
Your browser may be displaying a locally cached version of the page. Some sites also apply geo-blocking or bot-protection rules that affect automated checkers but not regular browsers. If our tool reports a site as down but you can open it normally, your local cache or ISP routing is likely involved.
