Is it down checker
Check whether a site is down for everyone or only for you.
Free and no signup. This one fetches the URL from our server; nothing about it is stored.
A HEAD request from our server, which is cheaper for the site being checked than loading the page. Nothing is stored.
About this tool
When a site will not load the first question is whether the problem is the site or your route to it. This requests the page from our server, which is on a different network, a different DNS resolver and a different ISP from yours — so a success here narrows the fault to your side, and a failure confirms it is not you.
- A HEAD request rather than a full page load: it answers the question and costs the site being checked almost nothing.
- A 403 or 503 means the server is up and refusing you. That is a different problem from a timeout, and worth telling apart before you start restarting things.
- We check from one location. A site can be down in one region and fine in another, so a green result here is not a guarantee for your users.
- Nothing is stored. The URL is used for the request and then discarded.
Questions
- Is the site down or is it just me?
- If this reports it up, the site is reachable from outside your network and the problem is local — DNS, a VPN, a firewall, or a cached error. If it reports down too, it is not you.
- What does a 503 mean?
- The server is running and deliberately refusing the request — usually maintenance, overload, or rate limiting. Very different from a timeout, which means nothing answered at all.
- Do you check from several locations?
- No, one. A regional outage or a geo-block can therefore look fine here while being broken for your users.
