We adopt the most advanced seismic isolation devices and is built to maintain datacenter functions even when hit by a direct seven-class earthquake on the Japanese seismic intensity scale.
We are also taking precautions against risks for urban flooding, such as those caused by the torrential downpours, which have become common in recent years. Full preventative measures are implemented, such as installment of flood-control panels in building entrances, and positioning of equipment such as incoming power units and machine rooms on the second floor or higher.

Each datacenter building receives high-capacity and high-voltage electricity through multiple lines, in principle. If one is severed, other lines will still provide sufficient power for operations.
In the event of a blackout, the combination of an uninterruptible power supply (UPS) device and a large emergency-use generator will be able to maintain power in the datacenter building until electricity is restored.

The entrances of datacenter buildings are equipped with security gates using contactless smart cards. Security personnel are always on duty and visitors are allowed entrance through face-to-face reception.
Specialist technicians are permanently on call in the central monitoring center of each datacenter building, and building interiors are under surveillance 24 hours a day, 365 days a year.
