Bytesnet

What Bytesnet does

Bytesnet B.V. is a privately held Dutch data center and cloud infrastructure provider founded in 1999 as the Groningen and Rotterdam Internet Exchange (GN-IX/R-IX) and formally incorporated as Bytesnet in 2008 to commercialize colocation services. The company operates two Tier III certified facilities — Datacenter Spaanse Kubus in Rotterdam and Data Competence Center d'ROOT on Zernike Campus Groningen (opened 2018) — delivering four core service lines: Colocation (housing and rackspace with private corridors, suites, and Twinning Solutions for redundancy), High Performance Computing (pay-per-use GPU environments based on NVIDIA A100 with oil immersion cooling), Cloud Computing (pure IaaS with virtual servers, storage, and security), and Connectivity (intra-datacenter, dark fiber via WDM, and Cloud eXchange). Differentiating infrastructure includes KyotoCooling free-air cooling, oil immersion cooling, SmartPower & Performance energy management (developed with Tuuring), waste heat recovery into Groningen's district heating network via WarmteStad, and a hydrogen power pilot.

The business model combines recurring subscription revenue (colocation, cloud IaaS, connectivity) with usage-based HPC billing and professional services such as SmartHands. Go-to-market is predominantly direct enterprise sales, supplemented by an ICT service provider partner program offering co-branded resale, and a community-led Data Lab model at d'ROOT that engages students, researchers, and businesses in big data, AI, and sustainable IT projects. Customer segments are concentrated in Dutch healthcare (Erasmus MC, iDNA, Intermax HealthCloud), research and academia (ASTRON, University of Groningen, Hanzehogeschool, Noorderpoort), and government (Gemeente Rotterdam), served under Dutch data sovereignty. In 2024, Eurofiber acquired Bytesnet's datacenters, marking an ownership transition while the Bytesnet brand remains operational.
