Where Cloud Is Ground offers an ethnography of the international data storage industry and an inquiry into the relationship between data and place. Based in Iceland, which is fast becoming a hot spot for data centers--facilities where large quantities of data are processed and stored--the book traces the fraught work of siting data's material manifestations in relation to landforms and earth processes, local politics, national narratives, and still-open questions of spatial justice and sovereignty. Doing so, it unsettles techno-utopian ideals of connectivity and offers a window into what it means to live with our data, in a place where more and more data now lives.
