Network layer performance and security provided by a distributed cloud computing network

A distributed cloud computing network that includes a plurality of computing devices, comprising:

• a first one of the plurality of computing devices of a first data center that includes a first non-transitory machine-readable storage medium that provides instructions that, when executed by a processor of the first computing device, cause the first computing device to perform first operations comprising:
• receiving a first IP packet, wherein the received first IP packet is destined to a first origin server of a first origin network, wherein the received first IP packet has a first destination IP address, and wherein the first computing device does not have a private network interconnect (PNI) connection with the first origin network;
• processing the received first IP packet at the first computing device;
• determining that a second data center has the PNI connection with the first origin network;
• encapsulating the processed first IP packet inside a first outer packet to generate a first encapsulated packet that uses IP as a transport protocol;
• transmitting the first encapsulated packet from the first data center to the second data center that has the PNI connection with the first origin network;
• and
• a second one of the plurality of computing devices of the second data center that includes a second non-transitory machine-readable storage medium that provides instructions that, when executed by a processor of the second computing device, cause the second computing device to perform second operations comprising:
• processing, at a second computing device, the first encapsulated packet including decapsulating the first encapsulated packet to reveal the first IP packet;
• and
• transmitting the first IP packet to the first origin server of the first origin network over the PNI connection.
