Check whether a site is up right now from our server: the status code, response time and final URL after redirects.
How to use the Is it down?
- Enter a URL.
- See the status and response time.
- If it is up here but not for you, the problem is likely your network or DNS.
Down for everyone or just you?
A 200 here means the site answers from the internet. If you still can't reach it, try another network, clear DNS cache, or check whether your ISP or a firewall blocks it.
What the result means
"It's up" means the server answered with a status below 500 within 15 seconds, after following any redirects. A 200 is fully up. A 4xx such as 403 or 404 still counts as up: the server is running, but that page is blocked or missing. "It looks down" means a 5xx error, or no answer at all; then you see the reason, such as a timeout, a DNS failure or a refused connection. Response time is measured from our server, so under 1 second is healthy and several seconds suggests the site is struggling.
If it really is down
A DNS error usually means the domain expired or the nameservers changed; check the WHOIS lookup. A connection refused or timeout points at the server or hosting. A 502 or 504 means a proxy or CDN in front of the site can't reach the app behind it. A 503 often means maintenance or overload. If it is your site, check your host's status page and recent deploys first. Run the check again in a minute; short blips are common.
