SouthernCrossAI (SCX) says it is now providing “sovereign” AI inferencing capacity to Equinix’s Fabric AI ecosystem, making its inference nodes available to organisations connected to Equinix Fabric across the region.
The announcement positions SCX’s infrastructure as accessible via private connections through Equinix Fabric, which Equinix describes as a software-defined interconnection service. SCX said this would allow customers to connect to its ASIC-accelerated inference nodes without routing traffic over the public internet or using overseas cloud environments.
The company said the move builds on an existing operational SCX node at Equinix’s SY5 IBX data centre in Sydney, and that Equinix Fabric will act as the interconnection backbone for SCX’s planned multi-site expansion. SCX said additional nodes at Equinix facilities around Australia are expected to be brought online progressively through 2026 and beyond.
Equinix Australia interim managing director Chris Johnston said the company is adding SCX to the Equinix Fabric AI ecosystem as part of providing locally governed AI inferencing options that align with Australia’s data sovereignty requirements.
SCX CEO and co-founder David Keane said the Equinix Fabric connection would allow organisations already connected to the platform to reach SCX inferencing nodes via private, direct connections, with the intent of keeping Australian data onshore.
SCX also confirmed that its national expansion will incorporate SambaNova’s next-generation SN50 Reconfigurable Dataflow Unit (RDU) hardware, which the company described as designed for “agentic AI inference” workloads. SCX said the rollout of additional capacity is planned across 2026 and 2027, with access via Equinix Fabric from Sydney, Melbourne, Brisbane and other locations.
In the release, SCX cited performance, throughput and power claims for the SN50 compared with NVIDIA’s Blackwell B200 GPUs, and said the platform’s architecture supports large model sizes and long context lengths, with the ability to switch between models quickly for multi-model workflows. It also said the SN50 is expected to begin shipping to customers in the second half of 2026.
SambaNova chief revenue officer Harry Ault visited Sydney to progress the partnership, SCX said, including meetings with customers, government stakeholders and ecosystem partners to discuss sovereign AI infrastructure in Australia and the broader Asia-Pacific region.
