Abstract
Systems, methods, and software for operating one or more content delivery nodes (CDN), which cache content for delivery to end users, are provided herein. In one example, content requests received from at least a first end user for the content at a first CDN are monitored to determine when the content requests comprise an attack on the first CDN. Responsive to the attack on the first CDN, a rate limit is established in the first CDN on at least the content requests received by the first CDN and an indication of the attack is transferred for delivery to at least a second CDN. Responsive to the indication of the attack, the rate limit is applied for further content requests received for the content at the second CDN.
