Infrastructure
NVIDIA HGX B300 servers in our own facility in Bulgaria, each reserved for one customer. Below: the hardware, how you will reach it, and the status of every statement about the facility.
Hardware
Each server is an NVIDIA HGX B300 platform with 8 × NVIDIA Blackwell Ultra GPUs. The figures are NVIDIA’s and apply to one server; every compute figure says whether it is dense or sparse.
| GPUs | 8 × NVIDIA Blackwell Ultra (SXM) |
|---|---|
| GPU memory | 2.1 TB HBM3e in total |
| NVLink | 1.8 TB/s per GPU; 14.4 TB/s in total |
| FP4 Tensor Core | 108 PFLOPS dense; 144 PFLOPS sparse |
| FP8 / FP6 Tensor Core | 36 PFLOPS dense; 72 PFLOPS sparse |
| FP16 / BF16 Tensor Core | 18 PFLOPS dense; 36 PFLOPS sparse |
| Networking | 1.6 TB/s |

Access model
Planned
From 2027, customers will get:
- whole servers (bare metal) with Ubuntu, NVIDIA drivers and CUDA installed;
- root access for their own team;
- managed Kubernetes or Slurm across several servers, when the workload needs it;
- access from allow-listed IP addresses, with named accounts and MFA.
Virtual machines are not part of the service at launch.
The facility
Our own facility in Bulgaria. Planned measures are in the future tense until they are in place.
| Topic | What we say | Status |
|---|---|---|
| Location | Our own facility in Bulgaria | Confirmed |
| Room | A dedicated, access-controlled server room | Confirmed |
| Logical access | Named accounts with MFA, from allow-listed IP addresses; access logs kept for five years | Commitment |
| Geo-blocking | Access from restricted jurisdictions is blocked | Commitment |
| Operations | Will be monitored 24/7, with an on-call engineer | Planned |
| Physical access | Will have two-factor physical access, an intrusion alarm and CCTV | Planned |
| Power | Will run on UPS-protected power | Planned |
| Cooling | Will have redundant cooling | Planned |
| Network | Will connect over dedicated fibre | Planned |
Statuses as of 28 October 2026.
What we do not publish
We do not publish the address of the facility, photographs or plans of it, or details of our network. Keeping them private is part of its physical security.
