When AWS, Microsoft Azure, or Google Cloud falter, thousands of European businesses grind to a halt. Within minutes, chatbots, voice response systems, and CX platforms become inaccessible. What if the real question is not "when" the next outage will occur, but "how long" your business can afford to be offline?
The Hidden Vulnerability of European Digital Infrastructure
In recent weeks, several major outages have struck US giants of cloud infrastructure. Amazon Web Services (AWS), Microsoft Azure, Cloudflare: players renowned for their robustness saw their services abruptly interrupted, paralyzing thousands of businesses worldwide.
The scenario is now familiar. Within minutes, entire segments of the digital landscape become inaccessible. But behind these isolated incidents lies a much deeper structural risk: the massive dependence of European businesses on a restricted number of American players.
When a Critical Link Fails: The Domino Effect
When a global infrastructure encounters a technical incident, the consequences are immediate and devastating:
Customer Experience (CX) platforms freeze completely
Interactive Voice Response (IVR) systems stop answering calls
AI-powered chatbots disappear from websites
Business APIs become unavailable, blocking critical processes
Support teams find themselves without any means to serve their customers
For a business that has outsourced its entire customer infrastructure to the cloud, an outage of just a few hours can translate into substantial financial losses, not to mention the impact on reputation and customer satisfaction.
On October 20, 2025, the AWS outage paralyzed the internet for over 14 hours, affecting services as popular as Snapchat, Reddit, and banking applications. Less than two weeks later, Microsoft Azure suffered an 8-hour outage of its own, impacting millions of users worldwide.
Invisible Dependence: When "European" Does Not Mean "Sovereign"
Many companies underestimate the depth of their technological dependency chains. An often overlooked reality: the majority of solutions on the European market rely more than 80% on global infrastructures, even when they claim to be "European" or "sovereign."
This dependency affects every level of the technology stack:
Cloud hosting (AWS, Azure, Google Cloud Platform)
Content Delivery Networks (CDNs) (Cloudflare, Akamai)
DNS management and network routing
Security services and DDoS protection
Telecommunications infrastructures
The result: a solution presented as "local" may in reality depend on dozens of third-party American services, creating just as many potential points of failure.
At the digital sovereignty summit held this Tuesday, November 18, in Berlin, Emmanuel Macron declared that Europe refused "to be a vassal" of the United States and China.
Digital Sovereignty and Resilience: Beyond Ideology, an Operational Necessity
Digital sovereignty is not just a political or regulatory issue related to GDPR. It is, above all, an operational continuity challenge that directly impacts a company's ability to serve its customers under any circumstances.
The benefits of a truly sovereign infrastructure are concrete and measurable:
1. Guaranteed Service Continuity
In the event of a global incident, businesses that control their infrastructure retain their operational capacity. Their customers can continue to call, interact, and perform transactions.
2. Complete Data Control
Customer data remains within the national territory, under the direct control of the company, without transitioning through servers located outside the European Union. This control is even more crucial in light of the risks posed by the US Cloud Act, which allows US authorities to access data hosted by US companies, even when physically stored in Europe.
3. Reduction of Hidden Dependencies
Fewer intermediaries mean fewer potential points of failure and a better understanding of the entire technical chain.
4. Incident Absorption Capacity
A resilient architecture allows a technical incident to be absorbed without interrupting customer service, thanks to redundancy and direct control of the infrastructures.
💡 To go further
Digital sovereignty can no longer be a simple marketing pitch. It must become a measurable, verifiable, and certifiable standard.
In this discussion, Jean-David Benichou (CEO & Founder of ViaDialog) and Léonidas Kalogeropoulos (Open Internet Project / Numérique France Garanti) explore how to transform a commitment of principle into concrete industrial proof.
The ViaDialog Model: Operator, Host, and Software Vendor for Maximum Resilience
Faced with this challenge, some French players have chosen full control of the value chain. This is the case for ViaDialog, which has adopted a rare positioning in the digital customer relations industry.
Telecom Operator: Voice Routing Control
ViaDialog directly controls voice routing and telecom flows. Unlike the majority of market solutions, no invisible intermediary routes calls or interactive voice services. This control guarantees consistent and predictable service quality.
Sovereign Host: Infrastructures in France
ViaDialog solutions run on sovereign infrastructures located in France. The critical blocks do not rely on AWS, Azure, or Google Cloud, but on French datacenters.
This approach is reinforced by ISO 22301 certification, a stringent international standard for business continuity and crisis management. This certification validates that a business continuity management system is indeed implemented and regularly tested.
Software Vendor: In-House Development of AI Engines
Artificial intelligence engines, interactive voice response systems, omnichannel workflows, and customer journey orchestrators are entirely designed and operated in-house.
This complete vertical integration of the technology stack drastically reduces the number of intermediaries and, consequently, potential points of failure.
Structural Resilience: When Global Outages Do Not Impact Your Customers
The direct consequence of this sovereign architecture is a significantly higher structural resilience than that of solutions relying on global infrastructures.
Concretely, when a global infrastructure like AWS or Cloudflare experiences a major incident:
ViaDialog clients do not grind to a halt
Their users continue to call and be served
Their digital journeys remain active across all channels
Their customer service does not suddenly vanish
This difference is not theoretical. It is measured in minutes and hours of effective uptime while other platforms are offline.
Cloud Infrastructure: Not All Solutions Are Created Equal
It is important to emphasize that no platform is completely infallible. Zero risk does not exist in IT. However, not all solutions share the same risk profile when it comes to dependencies.
A company that entrusts its entire customer relations infrastructure to a platform relying 80% or more on AWS implicitly accepts that its customer service could be interrupted during an Amazon outage. This is a choice that must be made knowingly.
Conversely, a truly sovereign and diversified architecture offers structural protection against these systemic risks.
DORA: A Regulatory Framework Reinforcing the Importance of Resilience
For companies in the financial sector, digital operational resilience is no longer optional. The DORA regulation (Digital Operational Resilience Act), which entered into force on January 17, 2025, imposes strict requirements for managing information and communication technology (ICT) risks.
DORA notably requires:
The identification of all critical ICT (Information and Communication Technology) third-party service providers
The documentation of realistic failure scenarios
The implementation of credible exit strategies
Regular testing of operational resilience
As specified by the Prudential Supervision and Resolution Authority (ACPR),
"the ACPR will ensure that entities maintain governance and internal control frameworks in line with DORA requirements to guarantee effective and prudent management of ICT risk."
Sovereign Hosting: A Strategic Question for the Years Ahead
The question is no longer whether new major outages will occur, but when. In this context, every business must ask itself a strategic question:
Can we afford, in the years to come, for vital blocks of our customer service to rely entirely on infrastructures that we do not control?
For some organizations, the answer will be yes. Relying on US tech giants offers undeniable advantages in terms of scale, features, and sometimes cost.
But for others, particularly in regulated sectors (banking, insurance, healthcare, public sector), or for businesses where service continuity is absolutely critical, sovereignty and resilience become non-negotiable imperatives.
Technological Control: A Strategic Choice, Not a Marketing Slogan
Digital sovereignty is not about displaying a local flag on a website or communicating about "local" datacenters that, in reality, depend heavily on US infrastructures.
True sovereignty involves:
Control of network and telecom blocks (routing, numbering, interconnections)
Hosting on infrastructures truly independent of US hyperscalers
In-house development of critical technologies (AI, orchestration, security)
Appropriate certification and governance (ISO 22301, HDS, SecNumCloud...)
This is a substantial investment that requires rare skills and a long-term vision. But it is also the only way to guarantee true structural resilience.
Anticipating Rather Than Reacting
Recent outages among US cloud giants are not anomalies. They are symptoms of a hyper-centralized global digital ecosystem, where a few players hold massive market shares.
For European businesses, dependency on these global infrastructures represents a growing operational risk. As customer relations digitize and consumer expectations for availability rise, the ability to maintain continuous service, even during major incidents, becomes a competitive differentiator.
Digital sovereignty and resilience are no longer optional. They are strategic imperatives for any business that takes its continuity of operations and the protection of its customer data seriously.
