At the opportunity of connecting to the Saga Node of SINET4, Saga university rearranged the structure of the network system, by out-sourcing and utilizing a data center service. The purpose of the rearrangement is to improve the network availability. In other words, the rearrangement installed the redundant routes for our two main campuses and improved the preparation for fails in electric power supply and disasters. The domain name services were also rearranged for improving their safe services.
