Microsoft outage revives EU push for tech sovereignty

A Microsoft outage that lasted nearly 24 hours knocked out Outlook, Teams and Copilot for millions of users in 74 countries. It happened just as EU leaders met in Dublin to discuss artificial intelligence, and it set off a new round of calls in Europe to control its own digital infrastructure. Analysts and lawmakers also said the failure showed the risk of relying on a handful of cloud providers for basic office work.politico.eu

The problems started around noon Eastern time on Thursday, November 12, and spread worldwide within an hour. Microsoft later said the incident was "a technical issue not related to cyber or AI / agents". It traced the cause to a problem during an earlier network capacity upgrade. The company apologized, and by Friday afternoon it said it was "seeing broad recovery".afp.com+2

Sovereignty push in Dublin

"Only 20% of European digital services run on European infrastructure," Mistral CEO Arthur Mensch said on Friday after addressing EU leaders. He argued that money spent on U.S. or Chinese technology "could be reinvested here, on infrastructure we control". French President Emmanuel Macron wrote on X that "our independence cannot be outsourced. It must be built here at home, in Europe."politico.eu

Finnish MEP Aura Salla said Europe has "outsourced too much of our digital infrastructure to actors outside the EU," and called for public contracts to favor European technology. German Social Democrat Johannes Schätzl said digital sovereignty "must be measured by whether we can remain operational even during outages like this." The main EU institutions largely came through unscathed. Amazon Amazon.com, Inc. ↘ 0.29%, Microsoft and Google Alphabet Inc. ↘ 0.96% together hold about 70% of the European cloud market, while European providers hold roughly 15%, according to Synergy Research Group.politico.eu+2

Concentration risk in focus

The disruption reached far beyond email inboxes. Euronext reported email problems and Aviva switched to backups for its earnings calls. In Taiwan, one financial firm confirmed trades by fax. Irish security consultant Brian Honan told RTÉ that relying on a single provider means "you have concentrated risk."rte.ie

Gartner ↗ 0.69% analysts wrote that Microsoft 365 has become "the connective tissue" linking corporate identity, security and AI workflows, so a single failure can spread across a whole company. Forrester ↘ 0.22% said bundling services under one vendor "creates systemic fragility". It added that the outage previewed what could happen if a foreign government ordered services cut off. Bangkok Post reported that the outage had revived concerns in Asia as well about businesses' need for backup systems.bangkokpost.com+2

Some analysts questioned whether customers will actually leave, given the steep cost of replacing tools so deeply embedded in daily work. Sebastian Toffaletti of the Digital SME Alliance called the outage a "reminder of the systemic risk created by concentrating digital infrastructure with a few global tech giants."politico.eu
