Zion attempted to put an emergency firewall system in place to protect their network interfaces from the Machines, but the Machines quickly bypassed the new System, and inserted viral routines into the Zion network, impairing their communication system.

Cypherites continued stealing information from Zionite data clusters, despite increased resistance from Zion.
