Is this website down?

Enter a URL to check if a website is down for everyone or just for you. We request the page from our servers and report the HTTP status code, response time and redirects. Free, no signup.

How to check if a website is down

  1. Type the domain or full URL in the field above (https:// is added automatically).
  2. We send a real HTTP request from our infrastructure, independent from your network, browser and DNS.
  3. Read the result: a 2xx/3xx/4xx answer means the server is up; a 5xx error, timeout or connection failure means it is down.

Down for everyone or just me?

If our check says the site is up but you still cannot open it, the issue is between you and the server: local DNS, ISP routing, firewall, browser extensions or a regional block. If our check fails too, the website itself (or its hosting, CDN or DNS provider) is having an outage.

What the results mean

200–299
Up. The page answered normally.
301 / 302
Redirect. We follow up to 5 redirects and show the final URL.
401 / 403 / 404
The server is up but the page is protected or missing.
500 / 502 / 503 / 504
Down. The server or its gateway is failing.
Timeout
No answer within 10 seconds — the site is unreachable or overloaded.

Stop checking manually

A one-off check tells you about right now. To know the moment your own site goes down, set up continuous monitoring: UptimeFlux checks every minute and alerts you by email, SMS, Slack or webhook.

FAQ — website down checker

How do I know if a website is down for everyone or just me?

Run the URL through this checker. It tests from our servers, not your network. If we get a valid response, the site is up and the problem is local to you (DNS, ISP, VPN, browser). If we cannot reach it, the site is down for everyone.

Why does a 404 count as "up"?

A 404 is an answer from a working web server: the server is online, only that page is missing. Outages show up as 5xx errors, timeouts or connection failures.

Can I check internal or private sites?

No. For security, the tool only checks public websites on ports 80 and 443 and blocks private or local IP addresses.
