The seamless functioning of digital services, from banking to healthcare, increasingly relies on cloud infrastructure. But a recent, largely unseen vulnerability has come to light: the potential for regional outages stemming from centralized control points located far from the users they serve. This isn’t a question of where data is stored, but where it’s managed. A failure in a seemingly distant location, like a data center in Virginia, USA, can disrupt services across Europe, even when those services are intentionally hosted within the European Union to comply with data localization regulations. This issue highlights a critical shift in thinking about digital sovereignty – moving beyond simply storing data within a region to ensuring true operational sovereignty.
The core of the problem lies in the architecture of many cloud services. While companies may store user data in EU data centers – in cities like Madrid, Paris, Frankfurt, or Dublin – the underlying management of those resources, including access permissions, server scaling, and encryption key management, often remains centralized in the provider’s home region. This centralization creates a single point of failure. If a critical service, such as identity management (IAM) or Domain Name System (DNS), experiences an outage, the ability to process data regionally is compromised, impacting both the availability and resilience of those services. These are not merely technical inconveniences; they represent potential breaches of fundamental rights, such as access to essential medical records or banking services.
The GDPR and the Obligation of Resilience
The General Data Protection Regulation (GDPR) explicitly addresses the necessitate for robust security measures, including ensuring the availability and resilience of processing systems. Article 32 of the GDPR mandates that organizations implement “appropriate technical and organisational measures to ensure a level of security appropriate to the risk.” This includes a specific requirement to ensure the “ability to ensure the continued confidentiality, integrity, availability and resilience of processing systems and services.” The full text of Article 32 details these obligations.
A service interruption caused by reliance on infrastructure outside of the European Economic Area (EEA) isn’t simply a technical glitch; it’s a failure to meet these GDPR requirements. It represents an availability breach that can directly impact citizens’ rights and freedoms. The incident that prompted this scrutiny – the disruption of services despite regional data storage – underscores this vulnerability. It demonstrates that compliance checkboxes regarding data location are insufficient. True digital sovereignty demands the ability to operate and manage processing systems autonomously, without critical dependencies on infrastructure susceptible to external disruptions.
From Data Sovereignty to Operational Sovereignty
For years, the focus has been on data sovereignty – ensuring data is physically located within a specific jurisdiction. However, the recent events demonstrate that this is only half the battle. Operational sovereignty represents a more comprehensive approach, demanding the ability to independently operate and manage processing systems. This means minimizing, and ideally eliminating, critical dependencies on infrastructure located outside the EEA, where technical failures or legal decisions in other countries could compromise service availability. The concept of operational sovereignty is gaining traction as organizations and regulators grapple with the complexities of cloud computing and data protection.

Understanding the Risks of Centralized Control
The risk isn’t limited to technical failures. Legal challenges or geopolitical events in the location of centralized services could also disrupt operations. For example, a court order in the United States could potentially impact access to data or services managed from a US-based data center, even if the data itself is stored in Europe. This highlights the need for organizations to carefully assess the risks associated with relying on centralized cloud services and to implement strategies to mitigate those risks.
Recommendations for Data Controllers
Organizations utilizing cloud services must proactively address these vulnerabilities. The Innovation and Technology Division of the Spanish Data Protection Agency (AEPD) has outlined several key recommendations for data controllers:
- Review Impact Assessments (DPIAs): Thoroughly analyze existing Data Protection Impact Assessments to determine whether the risks of cross-border dependencies have been adequately addressed, particularly concerning service availability.
- Demand Transparency in Architecture: Request detailed information from cloud providers regarding the architecture of their services, specifically identifying which services are truly “regional” and which are “global.” A critical question to ask is: can your database authenticate users if a critical connection to the US is severed?
- Design for Disconnection: Implement architectures that can operate in “island” or “degraded mode,” maintaining critical functions locally even if the central control plane fails. This requires careful planning and investment in redundant systems and failover mechanisms.
- Diversification: Consider adopting multi-cloud or hybrid cloud strategies to avoid systemic single points of failure. Distributing workloads across multiple providers and environments can enhance resilience and reduce the risk of widespread outages.
The cloud offers significant advantages in terms of scalability, cost-effectiveness, and innovation. However, the ultimate responsibility for data processing remains with the organization that determines the purposes and means of processing. Ensuring resilience to global failures is no longer simply a best practice; it’s a fundamental duty of compliance with regulations like the GDPR.
Addressing the Challenges of De Facto Standards
Many organizations rely on a small number of dominant cloud providers, creating a situation where switching providers can be difficult and costly. These providers often operate as “de facto standards,” presenting a high exit barrier. However, this doesn’t excuse organizations from their responsibility to manage the risks associated with these dependencies.
The focus should be on accountability. In line with supply chain security regulations, organizations should demonstrate due diligence in managing the risks associated with critical dependencies on non-substitutable suppliers. This includes identifying and analyzing these risks in impact assessments, requiring providers to be transparent about their resilience measures, and implementing realistic mitigation strategies as part of a comprehensive contingency plan. These mitigation measures, such as architectures allowing for “degraded mode” operation or process continuity strategies, should ensure that essential operations can continue even in the event of a provider failure, particularly those operations that have a high impact on fundamental rights.
Spain, as a member state of the European Union, adheres to the GDPR and actively participates in initiatives to strengthen data protection and digital sovereignty within the EU. Europol’s page on Spain provides information on the country’s collaboration with European law enforcement agencies.
Looking Ahead: The Future of Operational Sovereignty
The pursuit of operational sovereignty is an ongoing process. It requires a collaborative effort between organizations, cloud providers, and regulators. As cloud technologies continue to evolve, it’s crucial to remain vigilant and adapt strategies to address emerging threats and vulnerabilities. The incident that highlighted these issues serves as a wake-up call, emphasizing the need for a more proactive and comprehensive approach to data protection and digital resilience.
The next step for organizations is to prioritize a thorough review of their cloud architectures and risk assessments. Regulators will likely increase scrutiny of cloud service providers and their compliance with GDPR requirements. Continued dialogue and collaboration will be essential to ensure a secure and resilient digital future.
