Is this site down, and why?
Enter a website and we check it from our server: DNS, the connection, HTTPS, redirects and response time. You get a plain answer: down for everyone, probably just you, or that we couldn't verify.
What this tool does
This tool checks a website from our server, one step at a time: it looks up the site's address in DNS, opens a connection to it, sets up a secure (HTTPS) connection, follows any redirects and measures how long the answer takes.
The answer says what the checks prove. A missing domain, broken DNS, a server error, a certificate problem or a redirect loop affects everyone, so the site is down for everyone. A working answer means the site is up, so if it won't load for you, the cause is probably on your side.
No answer at all is different: from one place we can't tell a site that is down from a site that drops traffic from our network, and we say so instead of guessing.
How to read the results
- The headline is the verdict: up, down for everyone, up but answering with an error, not reachable from our server, or couldn't verify.
- What we checked lists each step. A step that never ran, because an earlier one failed, is left out.
- Behind Cloudflare: for sites on Cloudflare's network we can't test the raw connection, so the HTTPS check stands in for it. A Cloudflare error page (520 to 530) means Cloudflare works but the site's own server doesn't.
- Response time is measured from our server, so it is not the time you would see. More than 3 seconds is flagged as slow.
Frequently asked questions
The site works for me but you say it's down. Why?
Results are kept for 60 seconds, so it may have just come back. Your browser may also show a saved copy, or your network may reach a different server. Check again in a minute.
You say it's up, but it won't load for me. What now?
Then the cause is most likely between you and the site: your connection, your DNS server, a VPN or a browser extension. Try another network, such as mobile data, and see the tips under the result.
Where do you check from?
From our server, which runs in Cloudflare's network, in the data centre that handles your request. That is one place, which is why a timeout is reported as “not reachable from our server” rather than “down”.
Do you store the sites I check?
No. Each result is kept for 60 seconds so that many people checking the same site don't overload it, and then it is gone. We don't keep a list of checks or of who asked.
Can I check a site's DNS or email setup too?
Yes: the DNS lookup shows a domain's records, and the domain report checks registration, email security and the certificate.
