"This illuminating report from journalist Pitron (The Rare Metals War) ... succeeds in exposing the unseen hardware and processes that keep the modern world running ... Anyone who's ever wondered where, exactly, "the cloud" is located will want to check this out."
--Publishers Weekly

"Guillaume Pitron recalls the origins of digital technology and explains how this new communication tool has catastrophic consequences on our environment ... What happens when you send an email? What is the geography of clicks? What ecological and geopolitical challenges do they bring without our knowledge? This is the subject of The Dark Cloud ... For two years, the journalist followed, on four continents, the route of our emails, our likes, and our vacation photos."
--Margherita Nasi, Le Monde

"In The Dark Cloud, Guillaume Pitron exposes the supposed immateriality of the internet as one of the more pernicious of tech bro delusions. ... rather than saving us from the destructive tendencies of capitalism, the digital realm intensifies them, with the tech companies committed to exponential, unplanned growth irrespective of the environmental consequences ...[The Dark Cloud] demonstrates convincingly that we can't flee from our messed-up analogue world into some digital alternative. Our problems are material - and they require material solutions."
--Jeff Sparrow, The Saturday Paper

"Today has two battlegrounds--carbon and silicon. In The Dark Cloud, journalist Guillaume Pitron explains the distinction between these two battlegrounds is a carefully crafted illusion. Our screens are not portals to an infinity beyond the material. Far from lacking a footprint, technology actually has an immense cost in resources, energy and environmental destruction ... Pitron is a master of articulating the material cost of the "immaterial" ... It's only through works such as Dark Cloud ... that laboriously map the immense, insatiable machine that we realise it's one minute to midnight on the doomsday clock, and we're all asleep. Well, here is your wake-up call."
--Jason Steger, The Sydney Morning Herald

"It reveals the environmental cost of a dematerialized sector. Between the strategies of the giants who keep us in the illusion of a clean internet and the difficulty of feeling pollution that has no taste or smell, the investigator reveals the underside of the internet."
