Is This Website Down?
Check whether a website is up from outside your network, with status code, response time, TLS details and server headers. Free online uptime check.
This check runs from our server, not from your browser, and is rate limited. Nothing you enter is stored. Private and internal addresses are refused on purpose.
What this tool is for
Answers the only question that matters when a site will not load: is it down for everyone, or only for you. The request comes from our server, so a positive result means your network, DNS or ISP is the problem rather than the site. This is one of the few tools here that needs a server, because the question is about the internet rather than about your data. The request is made from our server, rate limited, and nothing you enter is stored.
How to use it
- Enter the address.
- Read the status, the response time and the server that answered.
- If it loads here but not for you, the fault is between your machine and the site.
Frequently asked questions
It says the site is up, but I still cannot open it.
Then the break is local: DNS cache, VPN, ISP routing or a firewall. Try the site over mobile data. If that works, your normal connection is at fault.
What response time is acceptable?
Under 200 ms is quick, under 600 ms is fine, above two seconds visitors start leaving. Note that this measures the server answering, not the whole page rendering.
