Methods and system of traffic load balancing between a plurality of Points of Presence (PoP) of a cloud computing infrastructure are described. A first PoP of multiple PoPs of cloud computing infrastructure that provides a cloud computing service receives a packet. The packet includes as a destination address an anycast address advertised by the first PoP for reaching the cloud computing service. The first PoP identifies a network address of a second PoP that is different from the first PoP. The first PoP forwards the packets as an encapsulated packet to the second PoP to be processed in the second PoP according to the cloud computing service.

Traffic load balancing between a plurality of points of presence of a cloud computing infrastructure

A first computing device of a distributed cloud computing network receives an IP packet that is destined to an origin server of an origin network. The first computing device processes the received IP packet and encapsulates the IP packet inside an outer packet to generate an encapsulated packet, where the outer packet has a source IP address that is advertised as an anycast IP address at the distributed cloud computing network, and a destination IP address of an origin router of the origin network. The encapsulated packet is transmitted to the origin router.

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

A map of IP addresses of a distributed cloud computing network to one or more groupings is stored. The IP addresses are anycast IP addresses for which compute servers of the distributed cloud computing network share. These IP addresses are to be used as source IP addresses when transmitting traffic to destinations external to the cloud computing network. The map is made available to external destinations. Traffic is received at the distributed cloud computing network that is destined to an external destination. An IP address is selected based on the characteristic(s) applicable for the traffic and the map. The distributed cloud computing network transmits the traffic to the external destination using the selected IP address.

Selection of an egress IP address for egress traffic of a distributed cloud computing network

A compute server receives a request that triggers execution of a code piece out of multiple code pieces. A single process at the compute server executes the code piece, which is run in an isolated execution environment. Each other code piece runs in other isolated execution environments respectively and executed by the single process. The code piece, when executed, modifies a response to the request. The response is generated based at least in part on the executed code piece. The generated response is transmitted.

Cloud computing platform that executes code in a distributed cloud computing network

A GRE tunnel is configured between multiple computing devices of a distributed cloud computing network and a single origin router of the origin network. The GRE tunnel has a first GRE endpoint that has an IP address that is shared among the computing devices of the distribute cloud computing network and a second GRE endpoint that has a publicly routable IP address of the origin router. A first computing device receives an IP packet from a client that is destined to an origin server. The first computing device processes the received IP packet and encapsulates the IP packet inside an outer packet to generate a GRE encapsulated packet whose source address is the first GRE endpoint and the destination address is the second GRE endpoint. The GRE encapsulated packet is transmitted over the GRE tunnel to the single origin router.

For each network resource request received at a server of a cloud-based service, a determination of whether that request originated from a second network resource is made. For each such request where the network resource originated from the second network resource, a referrer indication is logged that indicates the second network resource is a referrer to that network resource. A network resource relevance dataset is generated based on the referrer indications of the second network resources. A relevance metric is associated with each second network resource based on a total number of referrer indications. A search request is received from a client device. Based at least in part on the network resource relevance dataset, search results are determined. The search results are transmitted to the client device.

Responding to search requests based on referrer

A compute server receives a first request from a client device that triggers execution of a first third-party code piece. The first request is directed to a first zone. A single process at the compute server executes the first third-party code piece. As a result of executing the first third-party code piece, a second request is generated that triggers execution of a second third-party code piece. The second request is directed to a second zone. The single process executes the second third-party code piece. A response is generated to the first request based at least in part on the executed first third-party code piece and the executed second third-party code piece. The generated response is transmitted to the client device.

Cloud computing platform that executes third-party code in a distributed cloud computing network

A first edge server of multiple edge servers of a distributed edge computing network receives a request from a client device regarding a resource hosted at an origin server according to an anycast implementation. The first edge server modifies the request to include identifying information for the first edge server prior to sending the request to the origin server. The origin server responds with a response packet that includes the identifying information of the first edge server. Instead of routing the response packet to the client device directly, one of the multiple edge servers receives the response packet due to the edge servers each having the same anycast address. If the edge server that receives the response packet is not the first edge server, that edge server transmits the response packet to the first edge server, who processes the response packet and transmits the response packet to the client device.

Intelligently routing a response packet along a same connection as a request packet

A compute server receives a request from a client device that triggers execution of a third-party code piece. The compute server is one of multiple compute servers that are part of a distributed cloud computing network. The request may be an HTTP request and directed to a zone. A single process at the compute server executes the third-party code piece in an isolated execution environment. The single process is also executing other third-party code pieces in other isolated execution environments respectively. A response is generated to the request based at least in part on the executed third-party code piece, and the generated response is transmitted to the client device.

A method and system for detection of security threats on network resources based on referrer indications are presented. A determination that a second request originated from a first network resource is performed based on second request information associated with a second request for a second network resource. In response to determining that the second request originated from the first network resource, a referrer indication that the first network resource is a referrer to the second network resource is logged. A third request for a third network resource is received. A determination that the third request is part of a cyber-attack on a second server is performed based at least in part on the referrer indication.
