NTT Data Opens 12MW JKT2A Data Center in Jakarta, Debuts APN Connect

NTT Data has opened a 12MW data center in Jakarta, its Jakarta 2 Annex facility (JKT2A), and paired the launch with APN Connect — a service it calls the first in Indonesia built on All-Photonics Network technology.

The numbers are concrete. JKT2A is a seven-story building covering 5,800 sqm (62,430 sq ft), part of NTT's Jakarta Campus. Rack densities reach 40kW. NTT said the facility uses advanced cooling technologies and will support hyperscale, enterprise, and high-density workloads — the kind of profiles AI and cloud deployments increasingly demand.

Plans for JKT2A were announced in May 2024. Roughly a year later, the facility is live.

What does APN Connect change?

APN Connect provides low-latency connectivity between JKT2A and JKT3, a neighboring campus facility. NTT said the service enables real-time data synchronization between the two sites. All-Photonics Network technology (a network architecture that uses photonics end-to-end for data transmission) has not previously been deployed in a commercial service in Indonesia, according to the company.

For operators running workloads across both buildings, that translates into tighter inter-facility coupling — replication, failover and distributed workloads behave as if the sites sit closer together than the physical distance implies.

What the executives said

Yasuhiro Kajiki, managing director, Japan and APAC for NTT Global Data Centers, framed the opening as both a capacity and connectivity play. He said: "The opening of JKT2A is an important milestone for our business in Indonesia and, more importantly, for the many clients we serve here."

Kajiki added: "By expanding our capacity and connecting the facilities through APN Connect, we are creating a more connected and resilient data center platform that gives our clients greater flexibility as their infrastructure needs evolve. We are proud to continue investing in Indonesia's digital future."

Doug Adams, president and CEO of NTT Global Data Centers, pointed to demand fundamentals. He said: "Indonesia is one of the most dynamic digital economies in Southeast Asia, and it is creating significant demand for scalable, highly connected digital infrastructure."

Adams continued: "The opening of JKT2A reflects our ongoing commitment to supporting clients' cloud, AI and digital transformation initiatives with resilient, high-performance infrastructure. Together with APN Connect, JKT2A strengthens our ability to deliver the scale, connectivity and reliability organizations need to accelerate innovation and growth."

The market context

The key specifications at a glance:

• Capacity: 12MW
• Footprint: 5,800 sqm (62,430 sq ft) across seven stories
• Rack density: up to 40kW per rack
• Workloads: hyperscale, enterprise and high-density
• Connectivity: APN Connect, low-latency link between JKT2A and JKT3
• Announced: May 2024

The 40kW rack density figure matters for the region. High-density racks, once the preserve of specialized HPC deployments, are now table stakes for AI training and inference clusters. A Jakarta facility designed for those loads from day one positions NTT to capture Indonesian AI demand rather than retrofit for it later.

The APN Connect launch is the more unusual part of the announcement. Photonics-based networking in commercial Indonesian data center services has no prior deployment, per NTT's claim, which gives the Jakarta Campus a differentiator most competitors can't quickly match.

What does this change for buyers? Enterprise and hyperscale customers in Indonesia gain a new high-density option on an established campus, with synchronization-grade connectivity between buildings — useful for hybrid setups that split workloads across sites.
