Microsoft Outage Intensifies Debate Over European Digital Infrastructure

A global system outage affecting Microsoft Outlook and Teams across 74 countries has re-ignited legislative scrutiny over the European Union's reliance on American technology conglomerates. Services began failing on Thursday afternoon, prompting UK medical practices to instruct patients to call by telephone for urgent appointments. Microsoft stated there was no indication of a cyber attack, while technical teams worked into Friday to restore full functionality.

The incident coincides with new parliamentary initiatives in Brussels aimed at altering public sector procurement habits. Members of the European Parliament presented a draft report this week regarding the proposed Cloud and AI Development Act. The legislative draft urges public institutions to prioritise cloud services supplied by European providers. Dutch Green MEP Reinier van Lanschot argued during the presentation that our critical systems run on someone else’s technology, and someone else can switch it off. Concerns over remote service suspensions previously intensified in June when American developer Anthropic briefly blocked European access to its Claude models to comply with US export rules, before restoring connections on July 1.

Data from Synergy Research Group shows that Amazon, Microsoft, and Google currently command approximately 70 percent of the European cloud infrastructure market. The share held by European vendors has fallen from 29 percent in 2017 to roughly 15 percent today, with major domestic firms such as Germany's SAP and Deutsche Telekom carrying 2 percent each. Broadly, an estimated 80 percent of digital infrastructure operating within Europe originates outside the trade bloc.

While Eurobarometer survey data indicates strong public approval for locally managed infrastructure—reaching 94 percent in Sweden, 93 percent in Finland, and 92 percent in Denmark—consumer and enterprise willingness to transition remains low. Eurobarometer noted that 76 percent of respondents in Denmark and 73 percent in Sweden expressed a readiness to pay higher fees for EU-based providers, compared to 45 percent in Bulgaria and 35 percent in Estonia. In industry research conducted by German digital association Bitkom, 85 percent of surveyed German businesses cited over-reliance on US cloud vendors, yet 71 percent actively use them. Research firm IDC reported that only 4 percent of European organisations plan to rely solely on domestic suppliers.

To build domestic capacity, the European Commission aims to triple EU data centre capacity within five to seven years. Bidding closed on Thursday for up to seven EU-backed artificial intelligence gigafactories. Regional players include French firm Mistral AI, which reached a 21-billion-euro valuation following a 3-billion-euro funding round led by Samsung in September, and STACKIT, owned by Germany’s Schwarz Group, which is constructing an 11-billion-euro facility in Brandenburg. In response to regulatory pressures, Amazon Web Services established its own European Sovereign Cloud operation in Brandenburg in January.

Parliamentary committees are scheduled to examine the draft report of the Cloud and AI Development Act on 1 December. Committee voting is provisionally set for mid-March 2027, preceding a plenary vote in April, while Microsoft announced it will issue a complete post-incident report once service restoration finishes.
