Within the growing literature on broadband development, much research has focused on infrastructure competition and spatial effects driving investment incentives in broadband provision. However, less attention has been paid to the geographical factors explaining very high capacity fibre based network rollout. The purpose of this paper is to examine these geographical effects of rollout of these networks by utilizing basic data mining techniques in conjunction with exploratory spatial data analysis. In explaining the rollout of these networks, the paper derives from the literature a geographical model on broadband provision and examines it empirically by focusing on the spatial and temporal effects driving very high capacity fibre-based network development in the Netherlands. The paper confirms previous research on market uncertainty and the techno-economics of broadband development, but shows, in addition, that more specific factors related to local effects and demand uncertainty are vital in explaining the rollout of very high capacity fibre-based network
