Meta — Clonee AI Data Center Campus

Meta's Clonee campus in County Meath was the company's first data center outside the United States, opening in 2012 and expanded continuously since. The campus now spans 288 MW of IT capacity across multiple buildings and serves as Meta's primary European AI infrastructure hub. It supports training for Llama large language models and runs inference for Facebook, Instagram, and WhatsApp AI features across Europe, the Middle East, and Africa.

The facility is powered by 100% renewable energy through power purchase agreements with wind farms in Ireland, the UK, and Scandinavia. Clonee houses custom-designed Meta AI Research SuperCluster (RSC) compute nodes and has integrated NVIDIA H100 GPU clusters for next-generation AI workloads. The data center operates under Ireland's Data Protection Commission oversight, making it central to Meta's EU-compliant AI processing infrastructure.

The campus has been expanded several times, with new buildings added in 2016, 2019, 2022, and 2024. Each expansion increased GPU density. The Clonee site benefits from Ireland's cool climate (reducing cooling energy costs), proximity to the Ireland-UK-France submarine cable landing, and access to skilled technical talent in the Dublin metro area.
