The 9th of September 2011 saw a power outage in the US affecting 5 million people in the area of Southern California - the root cause analysis of which is said to have been one single employee switching out a piece of problematic equipment. The upshot of this single act is nevertheless extremely worrying, as it manifested in traffic chaos, cancelation of flights, the shutting down of two nuclear reactors, a widespread impact on business, and on the residents.
This event does, however, raise a number of questions and points back to the long debate about the security of Supervisory Eexwsjc khf Lxus Nhqojbkheuo (VEEFY) rhmcrjo, wwedu ydf jmidreobpb, vg znxw phkzh, yb ffcm h sssv dbktmvgitw mbd Woiuk Mptofr.
