Cardiff datacentre row: park and ride site, online habits, and a 25-year Guardian letters legacy

The Guardian's letters page has sparked debate over Cardiff's datacentre controversy, with David Rennie pointing out a key balancing fact: Cardiff council is seeking a replacement site for the park and ride facility that services the city's main hospital. Rennie also challenges anti-datacentre campaigners to consider their own computer use, noting that much online activity relies on such datacentres. Meanwhile, Denis Jackson from Glasgow reflects on nearly 25 years of contributing to the Guardian's letters page, praising it as a unique forum for global, open, democratic discourse that 'beats howling into the cosmos.' The exchange highlights the complex trade-offs in technology and urban planning, from essential public services to the digital infrastructure underpinning daily life. As datacentre debates continue, the letters page remains a vital space for diverse voices to shape the conversation.
