European cloud operator Nebius this week announced its first deployment of Nvidia Blackwell Ultra AI infrastructure in the UK. The cluster sits in Ark Data Centres’ Longcross Park campus in Surrey. The cluster totals 126 racks across three data center halls. The first phase comprises 4,000 Nvidia HGX B300 GPUs, housed within Nebius' self-developed Gen5 servers.
In a statement, Arkady Volozh, founder and CEO of Nebius, said: “This launch is a milestone for Nebius and for the UK’s growing AI ecosystem. By combining our cloud infrastructure foundations with Nvidia’s latest technology, we’re empowering organizations across the UK to train, deploy, and scale AI models and applications faster, more securely, and more sustainably than ever.”
In a statement, Basecamp Research co-founder, Oliver Vince, said: "Tackling unprecedented challenges like designing programmable medicines requires infrastructure that can handle massive proprietary datasets from across the globe while maintaining the speed and reliability to push scientific boundaries.
"Nebius's infrastructure delivers the scale and performance we need; having it here in the UK means we keep greater control over our data and can compete at the cutting edge of AI-driven life sciences.”
