A proper fix means that a failure like this causes you a headache, it doesn't close all your branches, or ground your planes, or stop operations in hospitals, or take your tv off air.
You do that by ensuring a single point of failure, like virus definition updates, or an unexpected bug in software which hits on Jan 29th, or when leapseconds go backwards, can't affect all your machines at the same time.
