Maximum 4 hours unscheduled downtime per critical system in any 12 months
Is this legally binding?
Binding, sectoral. Binding, but only for a defined population: one regulated sector, or the federal government and the vendors it buys from.
Binding obligation (FSM-N05 para 5 and equivalents): make all reasonable effort to maintain high availability; maximum unscheduled downtime for each critical system must not exceed a total of 4 hours within any period of 12 months. Binding on FIs only.
