The security of all our sites is designed according to their physical location, which creates different conditions and opportunities. The surroundings are part of the security systems, not least in Falun and Piteå where nature contributes with physical obstacles. All site locations are carefully selected with regard to factors such as floods, earthquakes, and the risk of being affected by other external events that could make operations more difficult or threaten the facilities. The buildings are placed on the plots to allow for large security zones. Our Main Site in Falun and both our Arctic Sites are located in areas with low risks of natural disasters and at a reasonable distance from the traffic that can cause accidents, i.e. airway corridors, railways, and major traffic routes. The two sites in Stockholm constantly replicate each other's content and are located in different parts of the city. The distance contributes to the level of security by reducing the probability of a simultaneous attack on both centers.
