Website Down Checker
A site will not load and you need to know whose problem it is. We request it from our network and tell you: down for everyone, blocking bots, or just unreachable for you.
How the check works
We send a real HTTP request to the address from our own network, follow up to five redirects, and measure what comes back: status code, response time, final URL and server signature. Because the request originates from an independent location, the result separates “the site is down” from “the site is down for me”, which is the question you are actually asking.
Reading the verdicts
A 2xx or 3xx answer means the server works; if it fails only in your browser, the fault is local and the report says where to look. A 4xx on a specific page with a working domain means the site is up but that URL is gone, which is a broken link, not an outage. A 5xx or a connection timeout is a genuine server-side failure. And a DNS resolution failure is the most serious signal of all: the domain itself may have expired.
When a site is not coming back
Sometimes “down” turns out to be permanent: hosting unpaid, domain dropped, owner unreachable. The report links straight to the latest snapshot in the Internet Archive so you can see the site as it was, and to our Wayback coverage checker which estimates how completely it can be reconstructed. Rebuilding dead sites from archives is our core service, so the diagnosis and the cure live one click apart.
Frequently asked questions
The checker says the site is up, but it will not load for me. Why?
Then the problem sits between you and the server: a stale DNS cache on your device, your ISP or office firewall, a VPN exit node the site blocks, or geo-restrictions. Flushing DNS, switching networks (try mobile data) or disabling the VPN resolves the vast majority of these cases.
What does "does not resolve in DNS" mean?
The domain name no longer translates to a server address, so no browser anywhere can open it. Typical causes: the domain expired, its DNS records were deleted, or the name servers are down. If the domain is gone for good, the content may still survive in web archives; check it with our Wayback Machine Checker.
The site answers 403 to your probe. Is it down?
Almost certainly not. A 403 or 429 to an automated request usually means bot protection (Cloudflare, WAF rules) is filtering non-browser traffic while serving real visitors normally. Open it in a regular browser to confirm.
Can you monitor my site continuously?
This tool is a one-shot check by design. For continuous monitoring use a dedicated service with alerting; and if your site is down because the developer vanished or the platform locked you out, that is exactly the situation our rebuild service exists for.
