How the Soviet OGAS Network Collapsed as the Cold War Ended in 1990

By 1990, the Soviet Union's ambitious OGAS system — designed to manage the entire national economy through centralized, real-time digital planning — was failing catastrophically. As regional centers from the Urals to the Baltic began asserting autonomy, they stopped transmitting data to the central mainframes in Moscow, cutting off the network's feedback loops. The central computers, receiving corrupted, delayed, or absent signals, began producing meaningless outputs and falling into processing errors. Engineers at the Institute of Cybernetics watched helplessly as terminals flooded with timeout and unreachable-node errors, signaling the breakdown of the system's core control architecture. This technical collapse mirrored the broader geopolitical fracturing of the Cold War era, marking a wider global shift from centralized command-and-control systems toward decentralized models of intelligence.
