Nebul Launches Cross-Border European Cloud Expansion Into Belgium
Machelen, Wednesday 28 October 2026
Nebul has established its second European cloud region in Belgium, deploying over 1,000 advanced liquid-cooled processors to deliver fully sovereign computing infrastructure compliant with European regulatory standards.
Strategic Infrastructure in Machelen
On Wednesday, 28 October 2026, Leiden-headquartered sovereign cloud provider Nebul announced its expansion from a single-region footprint into a multi-region European cloud architecture by establishing a new presence at Datacenter United’s facility in Machelen, Belgium [1][3][4]. The expansion centres on a high-performance SuperCluster housing more than 1,000 Nvidia Blackwell Ultra graphics processing units configured inside Nvidia GB300 NVL72 rack-scale systems [1][3][4]. Server hardware for the Belgian installation is supplied by Lenovo, a US$83 billion enterprise listed at rank 196 in the Fortune Global 500, which operates manufacturing facilities across 10 markets and research hubs in 11 markets [1]. Datacenter United provides the underlying facility infrastructure, including connectivity, high-density power delivery, and advanced liquid-cooling mechanisms essential for running dense rack assemblies [1][3][4].
Operational Architecture and Sovereign Compliance
The deployment of GB300 NVL72 rack-scale configurations enables the graphics processors to act as a unified, cohesive computing unit, establishing an optimised hardware baseline for modern enterprise artificial intelligence workloads and model inference [3][4]. Datacenter United’s Machelen campus offers Tier IV-certified resilience accompanied by service level agreement guarantees reaching up to 99.999%, alongside a low-latency network interconnect back to Nebul’s primary Dutch facilities [1][3][4]. Hardware procurement has commenced, though Nebul has not yet disclosed an exact go-live date for client operations [3][4][alert! ‘specific launch date for cluster activation has not been publicly released’].
Strengthening European Data Governance
Nebul’s cross-border step addresses growing regulatory friction surrounding algorithmic deployment, intellectual property safety, and cross-border data transfer rules governed by European Union mandates [1][GPT]. Prior to moving into Belgium, the Dutch company anchored its sovereign environment exclusively within Dutch facilities operated by Eurofiber, NorthC, and Switch Datacenters [3][4]. As European enterprises seek private AI hosting rather than shared multitenant services subject to non-European jurisdictions, Nebul Chief Executive Arnold Juffer noted that market demand currently exceeds the sovereign computing volume being built across the continent [1][3][4].
Optimising Full-Stack AI Workload Performance
To scale software platforms and enterprise inference efficiently, Nebul has paired its computing capacity with specialised infrastructure partners, previously incorporating NetApp as a foundational storage tier and running a Supermicro HGX B200 SuperCluster [3][4]. Expanding this ecosystem, Nebul partnered with DDN on 22 October 2026 to integrate the DDN Infinia storage engine alongside existing NetApp and VAST Data implementations [3][4]. The integration manages key-value caching across the entire graphics processing fleet, achieving token response speeds up to 5 times faster while reducing context reloading expenses by nearly 60 per cent [3][4]. With preparations underway for further cloud regions across the continent, this cross-border hub reinforces Europe’s broader push toward independent, high-density digital infrastructure [1][3][4].
