BT International, a global leader in international secure multi-cloud connectivity, and STACKIT, the cloud provider of Schwarz Digits, have announced a partnership to help multinational customers operating in the EU comply with regulations, enhance their operational resilience and achieve the best applications performance.
Initially, BT will provide internet connectivity (peering) from its existing global network into STACKIT’s EU-based sovereign cloud. Later, this will be complemented with the option of private connectivity. In future, both private and internet connectivity will be delivered by BT’s new Global Fabric network-as-a-service (NaaS) platform. This will enable on-demand, flexible and resilient connectivity to STACKIT and other cloud services.
For the first time, STACKIT’s private sovereign cloud will be accessible to organisations operating outside the EU via a private sovereign connection rather than public internet links.
This breakthrough offers EU-based multinationals with global operations greater flexibility and control over where their data and applications are hosted and who can access them — ensuring compliance while unlocking greater business value.
Multinationals headquartered outside the EU but conducting business within the jurisdiction will also benefit. They can now build resilient, sovereign IT infrastructures to support their European operations, with compliant access to critical data and applications in line with regulations.
STACKIT’s high-performance data centres, located exclusively in Europe, operate under stringent security protocols and are fully GDPR-compliant. This ensures that customers within the EU retain complete control over their data. STACKIT also provides robust recovery capabilities, safeguarding customers against outages caused by external events such as natural disasters.
Global Fabric connectivity will offer customers using STACKIT on-demand access to a full suite of secure, stable, scalable and sovereign multi-cloud networking services. It includes pre-integrated connectivity to the world’s leading cloud platforms, SaaS providers, security services, and other digital solutions.
According to the latest McKinsey Economic Conditions Outlook, executives say geopolitical instability “overshadows all other perceived economic risks” with 72 per cent of respondents to its February 2026 survey citing it as one of the biggest global economic risks, up sharply from 51 percent in December 2025.
Global Fabric supports sovereignty and resilience by giving customers full control over how their workloads and data traverse the network. By accessing STACKIT via Global Fabric, customers will be able to ensure their data remains within EU borders — even as it moves between clouds and users.
Ghoutam Banerjee, director partner ecosystem & growth, 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.”
Joris van Oers, chief commercial officer at BT International, said: “Sovereignty is top of mind for our customers — data sovereignty and both operational and technical sovereignty too. CIOs want resilient networks and IT systems to keep their businesses running, regardless of trade policy changes, global outages or natural disasters. We’re partnering with STACKIT to provide customers operating in Europe with trusted access to sovereign and resilient cloud services. It’s a powerful example of why BT is the global leader in secure multi-cloud connectivity.”
