ICT environment is requisite for our life and business. It is important to ensure toughness and robustness of ICT systems. To ensure toughness and robustness, there are several solution such as redundant configurations, SPoF (single point of failure) less wide-are distribution. Nowaday, we must design our system to endure beyond the scope of assumption of disaster caused by southeaster sea (Tounankai) earthquake. In this paper, authors design and evaluate a platform to evaluate disaster tolerance of ICT system by immitating existing disaster records. To contribute to make countermeasures against disaster and disorder more practical, they propose classification from a point of view of a topology and risk evaluations.
