We request https://stackoverflow.com/ every 2 minutes from New York, Stockholm and London. Any answer below HTTP 500 within 10 seconds counts as up, since large sites often answer automated requests with 403. A failure only counts once a second check confirms it.
What can I do when Stack Overflow is down?
Check Stack Overflow’s official status page for updates and try again in a few minutes. If stackoverflow.com works for us but not for you, try another network or browser, or clear your DNS cache. If your own product depends on Stack Overflow, tell your customers on your status page before they email support.

Our check shows that stackoverflow.com answers. Your own network, a VPN, browser extensions, an outdated app or a problem with your account can still break Stack Overflow for you alone.
