Acid Clouds: Mapping Data Centre Topologies explores the hidden infrastructures of digital life, exposing the political, ecological and social dynamics embodied by data centres. Moving beyond the sanitized image of the 'cloud', it unpacks the material and ethical complexities of these often overlooked data storage structures. Edited by Niels Schrader and Jorinde Seijdel, the book features essays from international authors who examines data centres through lenses such as artificial intelligence, machine learning, digital commons, decolonial practice, technodiversity, urban strategies, environmental impact, extractivism, algorithmic bias and digital capitalism. Roel Backaert's nighttime photographs of 101 Dutch data centres capture their imposing presence and question their concealed impacts. Together, these perspectives illuminate the power structures, environmental effects and cultural implications of data centres. Acid Clouds urges readers to reconsider the ethics of digital dependencies, posing vital questions: How can one rethink data ownership and control? In what ways do data centres influence identities and societal norms? How might it be possible to resist the extractive tendencies of digital capitalism and envision a more equitable digital future? The book challenges readers to critically engage with the hidden yet pervasive infrastructures that shape the world.
