Is it offline or just me?
Paste a link. We'll check it from our server to see if the site is really down — or if it's only you.
How the check works
When a website will not load, the useful question is whether the site is broken or your connection is. Your browser cannot answer that, because it only sees its own failure.
Enter an address above and our server requests it from its own network, then reports what came back: a normal response, an error status, a refused connection, a DNS failure or a TLS problem. Each of those points at a different culprit, and the verdict says which.
Frequently asked questions
What does "is it down for everyone or just me" actually mean?
A site can fail to load for two very different reasons: the site itself is broken, or something between you and the site is. This page tells the two apart by loading the URL from our server instead of your device. If we reach it, the site is up and the fault is on your side of the connection. If we cannot reach it either, the site is very likely down for everyone.
Why does a website load for other people but not for me?
Usually a stale DNS cache, a VPN or proxy, an ad blocker or browser extension, a corporate or school firewall, or your ISP having trouble reaching that particular network. Restarting your router, flushing your DNS cache, switching to another DNS resolver, or trying mobile data instead of Wi-Fi will fix most of these.
The checker says the site is up, but it still will not load. What now?
Try it in a private window with extensions disabled, then on a different network such as your phone on mobile data. If it works there, the problem is your local network, DNS or browser. If it fails everywhere but our check succeeds, the site may be geo-blocking or rate-limiting your address specifically.
What do the HTTP status codes mean?
A 2xx or 3xx means the server answered normally, so the site is online. A 403 or 429 means it answered but refused us, often bot protection. A 404 means that one page is missing while the site itself is fine. A 5xx such as 500, 502 or 503 means the server is reachable but broken or overloaded, which usually is an outage for everyone.
Can I check a site on my local network or an internal address?
No. Addresses like localhost, 192.168.x.x, 10.x.x.x and cloud metadata endpoints are refused on purpose. Our server sits on the public internet, so it could not reach your private network anyway, and allowing those lookups would turn this page into a scanner for internal systems.
Does a green result prove the site is up worldwide?
No. The check runs from one server on one network path, so it proves that path works at that moment. It cannot rule out a regional outage, a broken CDN edge near you, or the site blocking a country or address range. Treat it as a strong signal, not a guarantee.
