Website Uptime Checker
Free website uptime checker. Is a site up or down right now, or is it just you? One live request, with the HTTP status code and response time. No account needed.
3 free checks per day. No signup needed.
How this check works
A single live GET request from this tool's location, right now. It's a single-region snapshot, not a multi-region monitoring network, so treat a "down" result here as a strong signal, not the final word if you need to confirm an outage from several places.
How to check if a website is down
- 1Enter the website's URL or domain and run the check.
- 2We make one real request from our server and read the status code and response time.
- 3If it responds, the site is up for us; if it does not, it is likely down for everyone, not just you.
Reading the status code
The status code is the quickest signal. A 2xx means the page loaded, 3xxis a redirect, 4xx is a client error like not found or blocked, and 5xx is a server error. A 429 is a special case: the server answered but is rate-limiting the request, so we count it as up.
A single check vs. continuous monitoring
This page tells you whether a site is up right now, in this moment. An outage at 3am, while you are checking a different site, or over a weekend will not show up in a manual check. That is the gap continuous monitoring fills: it checks on a schedule and tells you the instant something changes.
Frequently asked
Is this checking from multiple locations around the world?
No, a single live request from one location. A site can be up from here and down elsewhere, or the other way around, if the outage is regional or routing-specific.
Why does a 429 status count as "up"?
A 429 means the server answered and is deliberately rate-limiting this request, which is proof it's running, not proof it's down.
How is this different from Expiroo's uptime monitoring?
This page runs one check when you click the button. Signed-in monitoring runs the same check on a schedule and alerts you the moment something changes.
How do I check if a website is down?
Enter the URL above and run the check. This uptime checker makes one real request and reports whether the site is up, along with its HTTP status code and response time. If it does not respond for us, it is very likely down for everyone.
How can I tell if a site is down for everyone or just me?
If this checker reaches the site from our server but you cannot, the problem is on your side, your network, DNS, or browser. If it also cannot reach the site, it is down more broadly, not just for you.
What does the response time tell me?
It is how long the server took to respond to our single request, in milliseconds. A slow response can hint at an overloaded server or a slow region, though a one-off number is only a snapshot; a trend over time is more meaningful.

Know about downtime before your visitors do.
A one-off check can't catch a 3am outage. Expiroo checks your site on a schedule and alerts you by email, Telegram, WhatsApp, or webhook the moment it goes down, or its SSL or domain is about to lapse.
