Ark Data Centres — Corsham AI Campus (Wiltshire)

Ark Data Centres operates a secure, purpose-built campus in Corsham, Wiltshire — a historically significant location for UK government communications infrastructure. The Corsham campus (designated A1 and A2 facilities) is one of the UK's most secure commercial data center sites, built to withstand significant physical threats and supporting OFFICIAL-SENSITIVE through SECRET-classified workloads under UK government security standards.

Ark holds IL2 through IL4 certifications under the UK Government Security Classifications (GSC) framework and is listed on the Crown Commercial Service G-Cloud framework. The Corsham campus serves UK Ministry of Defence, GCHQ, Home Office, and other central government departments requiring the highest levels of physical security and data sovereignty.

For AI workloads, Ark has positioned Corsham as a secure AI processing node for UK government departments undertaking AI modernization under the Government's National AI Strategy. Ark offers GPU-as-a-service within its secure perimeter, allowing government customers to run AI inference and analysis workloads on sensitive datasets without those datasets leaving UK sovereign territory. Ark also operates a second campus cluster in Farnborough, Hampshire (A3 and A4 facilities), providing additional capacity closer to London's financial district.

Ark's Corsham and Farnborough sites are core infrastructure in the UK's sovereign AI compute strategy, complementing the public AIRR (AI Research Resource) initiative at Edinburgh and the NVIDIA Cambridge-1 supercomputer. The sites are not accessible via public cloud but are available through government frameworks and Ark's managed services.
