Abstract
Some embodiments provide distributed rate limiting to combat network based attacks launched against a distributed platform or customers thereof. The distributed rate limiting involves graduated monitoring to identify when an attack expands beyond a single server to other servers operating from within the same distributed platform distribution point, and when the attack further expands from one distributed platform distribution point to other distribution points. Once request rates across the distributed platform distribution points exceed a global threshold, a first set of attack protections are invoked across the distributed platform. Should request rates increase or continue to exceed the threshold, additional attack protections can be invoked. Distributed rate limiting allows any server within the distributed platform to assume command and control over the graduated monitoring as well as escalating the response to any identified attack.
