Is it down for everyone or just me?

When a website will not load, the problem can be the site itself, the network in between, or your own device and connection. This checker requests the page from our server, which is independent of your network. If it loads for us but not for you, the problem is almost certainly local.

If the site is up but not loading for you

  1. Hard-refresh the page (Ctrl+F5 or Cmd+Shift+R) or open it in a private window to rule out a bad cache or extension.
  2. Flush your DNS cache: ipconfig /flushdns on Windows, or sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder on macOS.
  3. Try a different DNS resolver such as 1.1.1.1 or 8.8.8.8, in case your ISP's resolver is failing.
  4. Switch networks (for example Wi-Fi to mobile data) to see if your ISP is the issue.
  5. Disable your VPN or ad blocker temporarily.
  6. Still stuck? Run our internet troubleshooter.

If the site is down for everyone

  • 5xx errors (500, 502, 503, 504) mean the server or something behind it is failing. Site owners should check application logs, upstream services and recent deployments.
  • "Could not resolve" means DNS is broken or the domain has expired. Check WHOIS and DNS records.
  • Timeouts point at a firewall, overloaded server or network outage.
  • TLS errors usually mean an expired or misconfigured certificate. Test it with the SSL checker.

Frequently asked questions

Why does the site show 403 here but work in my browser?

Some sites block requests from data centres or automated tools with bot protection. A 403 still means the server is up.

Can I monitor a site continuously?

This is an on-demand check. For continuous monitoring, use a dedicated uptime monitoring service that checks from multiple locations.
