The Ministry for Digital Development has developed recommendations for protecting data centers against UAV attacks. The department divided the data center into three categories: K1 - strategic objects, the defeat of which could disrupt central functions of the government for a period of one hour; K2 - objects that ensure the operation of economically or socially important systems at the regional and sectoral level, the disruption of which can last from four hours; K3 - corporate data centers, damage to which will lead to significant losses for individual organizations without wide-ranging consequences for the state. Each category has its own protection criteria, including reduced visibility from the air, physical reinforcement, electronic warfare equipment and air defense systems. It is also recommended that some of the data centers be located underground. Experts called these recommendations effective. But they admit that if implemented, providers' services could become 10% more expensive without taking inflation into account.
