I understand the label.
Ok then, if the definition of a cascading failure is:
A cascading failure is a process in a system of interconnected parts in which the failure of one or few parts can trigger the failure of other parts. Such a failure may happen in many types of systems, including power transmission, computer networking, finance, human body systems, and bridges.
Cascading failures may occur when one part of the system fails. When this happens, other parts must then compensate for the failed component. This in turn overloads these nodes, causing them to fail as well, prompting additional nodes to fail one after another.
So how might that relate to our current topic of discussion?
