Window Zero
EXPOSURE GAPWindow Zero is the time the breach stayed in the open before anyone said so — the gap between when the attack was first discovered on the operator's leak site (t1) and when it was publicly disclosed (t2). The wider this window, the longer victims, staff and customers were exposed with no warning.
Attack Summary
In the early 1970s, MMWEC worked to gather and focus the collective strength of municipal utilities on issues and developments that were threatening the viability of public power in Massachusetts. Joint action led to the acceptance of municipal utilities into the New England Power Pool in 1973, giving municipals the right to joint ownership in the large, regional power plants under development by private utilities.
