The article explores the infrastructural conditions of (de-)growth, focusing on the internet as a case study. It argues that infrastructure studies remain underexplored in degrowth scholarship, despite the critical role infrastructure plays in enabling equitable human well-being. The internet, as a global infrastructure, exemplifies the tensions between its potential for societal value and its resource-intensive nature. The physical layer of the internet, including data centres and submarine cables, requires significant energy and material resources. The logical layer, governed by internet protocols and financial mechanisms, reinforces the logic of perpetual growth, making the internet inherently growth-dependent. The article draws on Science and Technology Studies (STS) and Large Technological System (LTS) research to highlight the embedded growth logic in infrastructures. It suggests that the internet's expansion is driven by the need to accommodate increasing data demands and the logic of perpetual growth. The article also discusses the materiality of the internet, emphasizing the need to move beyond the perception of the internet as an immaterial entity. It calls for a critical understanding of the internet's materiality, considering the political and social structures that shape it. The article concludes with a discussion of the implications of degrowth for the governance and materiality of the internet, suggesting that a more 'sober' internet could be achieved through greater efficiency and restrictions on harmful content. It also calls for further research on large-scale infrastructure in degrowth contexts. The article highlights the growth built-in mechanisms in the internet, including network-design and governance-financial, which reinforce the logic of perpetual growth. The internet's infrastructure is designed to scale indefinitely, with over-dimensioning strategies that reduce future investment and favor growth. The article argues that the internet's growth logic is deeply embedded in the global capitalist system, making it challenging to achieve a degrowth scenario. The article calls for a re-examination of the internet's role in economic growth and the need for alternative infrastructural models that prioritize sustainability and equity.The article explores the infrastructural conditions of (de-)growth, focusing on the internet as a case study.
