Sydney’s gateway to cloud-connectivity

NEXTDC's S3 Sydney data centre is under construction and is due to open to the public in 2022. Development Approval (DA) for S3 was granted in December 2019.

Located in Artarmon, less than 10km from the Sydney CBD, S3 Sydney will deliver more than 20,000m2 of I.T space to organisations, and critical local access to the leading public cloud platforms.

As Australia’s most cloud-connected and cloud-enabled data centre provider, we house Australia’s largest and network-rich ecosystem of ICT services partners enabling NEXTDC to offer our customers greater choice and quality assurance when it comes to building high-performance, highly reliable and scalable Hybrid I.T architectures.

S3 will form its own thriving, network-rich ecosystem which will interconnect directly to NEXTDC's S1 Sydney and S2 Sydney data centres, and seamlessly into NEXTDC’s national footprint.

As Australia's most reliable data centre operator, we continue to advance our commitment to building Australia’s most resilient, sustainable and operationally superior digital infrastructure platform. S3 will bolster the wider national footprint, ensuring we continue to deliver our customers a 100% uptime advantage, minimise energy consumption and optimise the overall efficiencies we drive for our customers.
