• STACKIT's EU cloud accessible through BT Global Fabric network-as-a-service platform • Data stays in the EU but access extends globally through BT's private connections The fact BT International has partnered with STACKIT, the cloud platform of Schwarz Group Europe's largest retailer to provide global connectivity to its EU-based sovereign cloud service. Initial access will be delivered through internet peering via BT's Global Fabric network-as-a-service platform, with private connectivity planned.

STACKIT operates data centres in Germany under EU GDPR frameworks, enabling non-EU enterprises to access compliant cloud infrastructure through BT's global network. The Assessment The partnership addresses a specific gap in sovereign cloud markets: enterprises that need EU-hosted, GDPR-compliant infrastructure but operate across jurisdictions. STACKIT benefits from BT's global network reach rather than having to build direct connectivity itself. For BT, sovereign cloud partnerships are a differentiation play in the increasingly commoditised NaaS market stacking network-as-a-service with cloud-as-a-service.

The model mirrors similar telco-cloud partnerships in Asia and the Middle East, where local sovereignty requirements intersect with multinational operational footprints. What to Watch Whether STACKIT's EU data residency model attracts non-EU customers facing similar sovereignty requirements such as UK firms post-Brexit or Middle East enterprises and if BT replicates the partnership public-source context with other regional cloud providers.
