1. A method in a distributed cloud computing network that includes a plurality of computing devices, the method comprising:
receiving a first IP packet at a first one of the plurality of computing devices of the distributed cloud computing network, wherein the received first IP packet is destined to a first origin server of a first origin network;
processing the received first IP packet at the first computing device;
encapsulating the processed first IP packet inside a first outer packet to generate a first encapsulated packet, wherein the first outer packet has a source IP address that is advertised as a first anycast IP address at the distributed cloud computing network, and wherein the first outer packet has a first destination IP address of a first origin router of the first origin network; and
transmitting the first encapsulated packet to the destination IP address of the first origin router.
