An example operation may include a system, comprising one or more of: receiving a heartbeat message from a peer VNFCI indicating a current operational state of active, when the VNFCI is in active state, determining a first network isolation indicator, by a network isolation subsystem, by checking if the VNFCI was network isolated while becoming active, sending a first heartbeat message to the peer VNFCI indicating a current operational state as active and network isolation boolean since active, obtaining a second network isolation indicator of the peer VNFCI from a heartbeat message datastore, sending a second heartbeat message to the peer VNFCI indicating the current operational state as active and a desired operational state as active when at least one of: the second network isolation indicator was yes, and the first network isolation indicator was no, and sending a third heartbeat message to the peer VNFCI indicating the current operational state as active and a desired operational state as active when at least one of: the VNFCI is not the preferred standby instance, the second network isolation indicator was no, and the first network isolation indicator was no.
