Activists from Dutch direct action group Geef Tegengas broke into the construction site of a Microsoft datacentre at Westpoort Amsterdam on Friday, climbing cranes, lighting flares, and hanging banners linking the facility to Microsoft contracts with the Israeli military and US Immigration and Customs Enforcement. Police used teargas and physical force to respond; one officer was slightly injured. Hundreds of protesters gathered on both sides of the perimeter fence. The break-in was distinct from but parallel to the "Stop Dirty Data Centres" campaign, a two-day pan-European mobilization involving more than 100 groups including national branches of Greenpeace and Friends of the Earth. That coalition's members stayed outside the fence at the Amsterdam site. Smaller affiliated protests occurred in Bristol, Berlin, Warsaw, and Zagreb, with more expected Saturday. The coalition's framing is straightforward: big tech and governments are racing to build energy-hungry AI infrastructure without meaningful public participation, transparency, or scrutiny. Campaign coordinator Owen Espley said communities across Europe are "being shut out of decisions that will shape their local environments and futures." The coalition stopped short of endorsing the break-in but called it "understandable." The anger is not abstract. Datacentres consume enormous quantities of electricity and water — activist Roos Molenaar cited Amsterdam's drinking water supply — while the benefits flow primarily to multinational tech companies and their shareholders. The ecological costs alarm climate scientists. The economic costs land on local energy bills. The labour conditions, as a recent Guardian/Investigate Europe investigation found, can be dangerous for construction workers building them. Governments have their own logic: tax revenues, geopolitical competitiveness with the US and China, and a national security framing for AI capacity. But this logic runs directly into a legitimacy problem. When the public bears the resource costs and environmental risks of infrastructure built to serve global corporations, and has no meaningful say in siting or scale, the gap between who decides and who pays becomes politically combustible. The US midterm elections this week offered a signal: nearly every proposed moratorium on datacentres on the ballot was approved by voters. That democratic channel does not yet exist in most European contexts, which helps explain why the action has turned physical. The Amsterdam break-in is a leading indicator, not an outlier. Microsoft and site owner Pure Data Centres both issued boilerplate statements respecting peaceful protest while condemning unlawful entry. Neither addressed the substantive demands — moratoria, transparency, community decision-making power — which is itself a data point about how seriously the industry takes the political risk.
