The invention relates to an abnormal access blocking system comprising a global load balancing (GLB) domain name system (DNS) server, a plurality of grids, and a control server. The control server monitors the plurality of grids, and, when the traffic for one grid (hereinafter, referred to as "the grid under attack") from among the plurality of grids momentarily increases, dynamically allocates at least one computing element of at least a portion of the other grids, excluding the grid under attack, from among the plurality of grids, to the grid under attack. In addition, the control server monitors general grids, and, when the traffic for the general grids temporarily increases, dynamically replaces the general grids with super-grids. The control server updates the GLB DNS server. |
