Is it down for everyone, or just you?
Enter a website and we check it right now from 15 locations on 6 continents. You see what every location got back: the status code, how long it took, the IP it reached and the certificate.
Want to know the moment it happens?

What is a website down checker?
A down checker asks a website for its home page from somewhere else than your computer. If it answers there but not for you, the site is up and the problem is between you and it. We ask from 15 places at once, so you also see when a site is down only in one part of the world.
It’s not just you
No location could reach it. The site, its server or its DNS is down. Tell the owner or the host.
Some regions only
It fails from one region and works from the others: a routing problem, a regional block, or one server of several.
Up, but closed to bots
The site answers with a bot challenge, usually Cloudflare’s. People can probably use it, monitoring can’t.
It’s just you
Every location reached it. Try another network or browser, clear your DNS cache, or check your firewall or VPN.
If it’s down only for you
- Try another network, for example your phone on mobile data.
- Clear your DNS cache, or try another resolver such as 1.1.1.1 or 8.8.8.8.
- Open it in a private window, to rule out extensions and cached files.
- If all 15 locations reach it and you still can’t, your network or ISP may be blocking it.
If it’s down for everyone
- Check your host’s status page and your server’s error logs.
- If only some locations fail, look at DNS and your CDN first.
- Send your host the link to this check: it shows what each location saw.
Fifteen real visits, at the same moment.
When you press Check, each of our 15 probes requests the page at the same second, the way a new visitor would: its own DNS lookup, a new connection, the full TLS handshake. Redirects are followed. Each location reports the HTTP status, the time, the IP it connected to and how many days the certificate has left.
Locations
Europe, North and South America, Asia, Oceania and Africa, on five different providers.
Same moment
All probes check in the same second, so a short outage shows up everywhere or nowhere.
Real requests
A normal web request to port 80 or 443. Error pages and bot challenges are recognised, not counted as up.
One answer
Down means most locations failed, on at least three continents. Anything less is called partial.
Why is a website down for me but not for others?
Usually something local: a stale DNS answer, your network, a browser extension or your ISP’s routing. If all 15 locations reach the site, the site itself is up.
How is this different from other “is it down” sites?
Most check from one server. We check from fifteen, on six continents and several networks, and show you every answer. A site that fails only from Asia is a different problem from a site that is down.
Do you check from my location?
No, from our 15 locations. That’s the point: it separates a problem with the site from a problem on your side.
What does “blocked by a firewall” mean?
The site answered with a bot challenge, usually from Cloudflare. People can probably use it, but monitoring can’t see it. Check and fix it here.
Can I share a result?
Yes. Every check gets its own link, kept for 7 days. Useful when you tell your host it’s down.
How often can I check?
A few checks per hour from your network, and one fresh check per site per minute for everyone. Within that minute you see the latest result. We only send normal web requests to ports 80 and 443.
Do you store what I check?
The address, the results and your IP address, for 7 days: the IP to limit how often one network can check, the rest so the link can be shared. See our privacy policy.
