Europe committed billions to sovereign compute capacity, announced in the period alongside other infrastructure decisions on the continent, including a billion-euro commitment to semiconductor production.
Sovereignty, in this context, has a practical definition: capacity installed on home territory, operated under home jurisdiction, so that essential services don't depend on a decision taken in another country.
The period supplied the justification in the form of an example. A frontier model was pulled offline under export controls and returned only after a foreign government's approval, and access restrictions based on a company's country of origin became a routine subject.
The counterpoint is the usual one for technological sovereignty projects: capacity built by political decision tends to cost more and arrive later, and the difference is paid by whoever uses it.
For companies operating in the region, what changes immediately is the expectation of local supply in the medium term, and the ability to require in a contract where data is processed.
