Troubleshooting tips for Stack Overflow

If our monitor reports Stack Overflow 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.
