Website Down Checker
Check from our server whether a website is up: status code, response time, redirects, server header and DNS.
Is this website down?
The URL is requested from our server, a different network than yours, with a 10 second limit.
What the Website Down Checker does
When a site does not load, the first question is whether it is down for everyone or just for you. A cached DNS entry, an office firewall, a browser extension or your ISP can all block a site that is working fine for the rest of the world. This checker requests the URL from our server, a different network, and reports what came back: the HTTP status, how long the answer took, where redirects ended up, the server software header and the IP addresses the domain resolves to.
The verdict is one of four. Up means the server answered with a success status. Up but redirecting means it answered, but on a different URL than you typed, which is normal for http to https or non-www to www but worth knowing when a redirect chain is unexpected. Down with a status code means the server is reachable but returning an error such as 500, 502 or 503, usually an application or hosting problem. Unreachable means no HTTP answer at all: DNS does not resolve, the connection was refused, the TLS certificate failed or the host timed out.
Each of those tells you where to look. A DNS failure points at the registrar or name servers, a timeout at the server or a firewall, a 5xx at the application, and a working check from here while your browser fails points at your own network or cache.
Step by step
- 01Enter the domain or full URL. A bare domain is checked over https.
- 02Click Check. The request is made from our server with a 10 second timeout.
- 03Read the verdict, then the status code and the response time underneath.
- 04If the site redirects, check the final URL and the number of hops; one hop is normal, three or more slows every visit.
- 05If the verdict is unreachable, the reason says whether DNS, the connection or the certificate failed.
Common questions
Something between you and the site is in the way: your DNS cache holds an old address, your network blocks the domain, a browser extension interferes, or the site blocks your country or IP. Try another network or device, flush your DNS cache, or open the site in a private window.
A 403 means the server refused our request. Many sites return it to anything that looks like an automated visitor, so a 403 is not proof the site is down for people. A 503 means the service is unavailable: maintenance mode, an overloaded server or a hosting outage.
The time measured is for the HTML of one URL from our server, including DNS, TLS and redirects, and excludes images, scripts and rendering. It is useful for spotting a slow server (over two seconds for the HTML alone) and for comparing before and after a change, not as a page speed score.
No. The check is made from the internet, so the site must be publicly reachable. Private addresses, localhost and intranet hosts are refused. Pages behind a login return a redirect or a 401, which the tool reports as such.
