The agreement will initially connect BT’s global network to STACKIT’s EU-based sovereign cloud through internet peering. It will later add private connectivity options and be integrated with BT’s Global Fabric network-as-a-service platform, creating a more controlled route for customers that need compliant access to data and applications hosted in Europe.
Private access for multinational customers
The companies said the partnership will make STACKIT’s private sovereign cloud accessible to organisations outside the EU through a private sovereign connection, rather than public internet links. This is intended to support companies that need to comply with European sovereignty requirements while managing IT infrastructure across multiple markets.
For EU-based multinationals with global operations, the arrangement provides more control over where data and applications are hosted and who can access them. For companies headquartered outside the EU but operating within the jurisdiction, it offers a way to support European operations with sovereign IT infrastructure and compliant access to critical systems.
STACKIT, the cloud provider of Schwarz Digits, operates data centres located exclusively in Europe. The company said its facilities run under GDPR-compliant security protocols, giving customers within the EU control over their data. STACKIT also provides recovery capabilities designed to protect customers from outages caused by external events, including natural disasters.
BT will expand connectivity through Global Fabric
BT will begin the partnership with internet connectivity from its existing global network into STACKIT’s sovereign cloud. The companies plan to add private connectivity at a later stage, followed by integration with Global Fabric.
Global Fabric will give STACKIT customers on-demand access to secure, stable and scalable multi-cloud networking services. The platform includes pre-integrated connectivity to cloud platforms, SaaS providers, security services and other digital services, allowing customers to connect to STACKIT alongside other cloud environments.
The integration is intended to give customers greater control over how workloads and data move across the network. BT said customers accessing STACKIT through Global Fabric will be able to keep data within EU borders as it moves between clouds and users.
Sovereignty and resilience shape demand
The partnership comes as multinational companies face closer scrutiny over data sovereignty, operational resilience and exposure to external disruptions. The press release cited McKinsey’s Economic Conditions Outlook, which found that 72% of respondents to its February 2026 survey identified geopolitical instability as one of the biggest global economic risks, up from 51% in December 2025.
Ghoutam Banerjee, director partner ecosystem & growth at STACKIT, said: “Through our partnership with BT, we are creating a groundbreaking connection for digital sovereignty. Together, we are enabling multinational corporations to access our sovereign STACKIT Cloud directly from locations outside the EU via a private sovereign connection. This integration not only strengthens our customers’ operational resilience but also guarantees full compliance with European data protection standards, while ensuring that data remains securely within EU borders.”
The partnership gives BT a role in connecting global enterprise networks to sovereign cloud infrastructure in Europe, while giving STACKIT a route to serve multinational customers that need access from outside the EU.
