Troubleshooting tips for Three
If our monitor reports Three is up but you still can't reach it, try these steps in order:
Hard-refresh your browser
- Press Ctrl + F5 (Windows) or Cmd + Shift + R (Mac) to bypass the cache.
- If that fails, open the page in an incognito / private window.
Clear cookies and cache
- Open your browser settings → Privacy / History.
- Clear cookies and cached files for the last hour, then reload.
Flush your DNS
- Windows: open Command Prompt and run ipconfig /flushdns.
- macOS: open Terminal and run sudo killall -HUP mDNSResponder.
- Linux: run sudo systemd-resolve --flush-caches (or systemctl restart nscd).
Restart your router
- Unplug the router and modem for 30 seconds.
- Plug them back in and wait until all lights are stable, then retry.
Try a different DNS or VPN
- Switch your DNS to 1.1.1.1 (Cloudflare) or 8.8.8.8 (Google).
- Use a reputable VPN to test from a different country — useful when the site may be region-blocked.
