What does "I'm Under Attack Mode" do?

"I'm Under Attack" will add additional protections to a site that is under attack and needs DDoS protection and mitigation. If you're under attack and have this feature enabled during the attack, visitors will receive an interstitial page for about five seconds while we analyze the traffic to make sure it is a legitimate human visitor.


Note: Visitors to the site must have JavaScript and Cookies enabled to pass the interstitial page.

Why am I getting a "Checking your Browser before accessing" message before entering a site on Cloudflare?

The "Checking your browser before accessing example.com" page occurs when the site owner has turned on this I'm Under Attack Mode setting. The page will generally go away and grant you access to the site after 5 seconds.

You will need to have both JavaScript and Cookies turned on in your browser to pass the check. The check is in place to make sure that you are not part of a botnet.
