In this article, the authors demonstrate how the data center has become a key site, object, and metaphor for interdisciplinary scholarship of the internet. While the data center is a fabrication of engineering, computer science, and cognate fields, it has been the critical gaze of scholars outside of those industries. Together, this scholarship has established the field of Critical Data Center Studies. Critiques of the data center – often thought of more generally as ‘internet infrastructure’, and more evocatively as ‘the cloud’ – have emerged from the social sciences, humanities, journalism, and the arts. The authors do this by answering questions about the current social, cultural, political, and environmental landscapes of the data center. Scrutiny of the foundational imaginaries of the internet, real estate deals by Big Tech, the industry’s enabling policies, their connections to energy and other public infrastructure – among many other factors – serves, at the very least, to situate the data center as a media object, as more than simply a material infrastructure, as more than data warehouse, and as more than ‘the cloud’. Further to this, the authors reflect on how the data center has been and continues to be studied, and why critical interventions have been so fruitful within a vast array of disciplines – from history and anthropology, to media studies, information studies, and science & technology studies – for shifting the focus from questions of infrastructural visibility to questions that weave together concerns of efficiency, policy, popular culture, and planetary devastation.
