Is It Down?

Down for everyone or just you?

Is the website down for everyone or just you?

When a site will not load, the first question is whether the problem is the website or your own connection. This checker answers both. It asks for the site from Cloudflare's global network, looks up its DNS records and, at the same time, tests whether your own browser can reach it. The verdict tells you in plain words whether the site is up, slow or down, how fast it answered and what most likely went wrong.

How to read the result

  • Up: the server answered with a working page in under 3 seconds.
  • Slow: it works but took 3 seconds or longer, which many visitors will not wait for.
  • Up, but returns an error: the server is online but the page answers with a 4xx code such as 404 or 403.
  • Down: a 5xx server error, a timeout, a refused connection or a domain that no longer resolves in DNS.

Common reasons websites go down

Most outages come from a handful of causes: the hosting server ran out of memory or disk, a deployment or plugin update broke the code, the database stopped answering, the SSL certificate expired, the domain was not renewed, or DNS records were changed by mistake. Cloudflare errors 521 to 524 mean Cloudflare itself is fine but cannot reach the origin server behind it.

What to do next

If the site is down for everyone and it is yours, check your hosting status page and error logs, then confirm the domain and certificate have not expired with our WHOIS and SSL tools. If the site is up for everyone but not for you, restart your router, flush your DNS cache, disable VPNs and extensions, or try mobile data. Use "Check again" after a minute to see whether the problem is still there.

Frequently asked questions

How does the checker decide if a site is down?

It requests the site from Cloudflare's network. Server errors (5xx), timeouts, failed connections and missing DNS count as down. A working answer slower than 3 seconds counts as slow, and anything faster as up.

The site is up here but not for me. What now?

Then the problem is on your side: try another browser, clear the DNS cache, restart your router, turn off VPN or ad-blocking extensions, or switch to mobile data. Your internet provider may also be blocking or misrouting the site.

What does "Up, but returns an error" mean?

The server answers, so it is online, but the page returns a client error such as 404 Not Found or 403 Forbidden. The site works; that particular address does not, or it blocks automated checks.

Does the checker save or monitor my website?

No. Each check runs once when you press the button. Results are cached for 60 seconds. For continuous monitoring with alerts, use an uptime monitoring service.
