A system for load management in a shared address networking architecture includes a primary point-of-presence (POP) group of servers configured to serve content of a domain and that are each reachable at an address of a first IP address block and a secondary PoP group of servers configured to serve the content of the domain and that are each reachable at an address of a second IP address block. The system further includes a traffic management agent configured to reduce a total volume of incoming requests received by the primary PoP group for a period of time following a return of a first server in the primary PoP group of servers to an online state by selectively directing a first percentage of the incoming requests to the second IP address block instead of the first IP address block.

Techniques are disclosed for managing gateway switchovers. An indication is received that a primary gateway will be switched to a backup gateway. In response to the indication, a response is made to a periodic health probe that a gateway switchover has been initiated. Incoming data traffic is forwarded from the primary gateway to the backup gateway. Subsequent to an elapsed time delay, a response is made to the periodic health probe that the primary gateway will no longer accept incoming data traffic. The time delay may be based at least in part on one or more of a time interval of the periodic poll and a time to effect the gateway switchover. The forwarding of the incoming data traffic from the primary gateway to the backup gateway is terminated.

Fast failover for gateway instances

Techniques for intelligently managing a virtual private network (VPN) gateway in a cloud computing system are disclosed herein. In one embodiment, an instance of a VPN gateway can query whether a logic lock on a network address is maintained by another instance via periodic renewal. In response to receiving a query result indicating that a logic lock on the network address is lost by the another instance, the instance can migrate a VPN connection originally handled by the another instance from the another instance to the instance such that a private network is connected to the instance via the migrated VPN connection to reduce downtime for accessing computing resources in the cloud computing system.
