# Extinction Rebellion Throws Acid-Filled Balloons at Microsoft Data Center Site in Amsterdam

_General · published 2026-07-19_

Climate activists affiliated with Extinction Rebellion claimed responsibility for an attack on a Microsoft AI data center construction site in Amsterdam, hurling water balloons filled with a mixture of hydrogen peroxide, acetic acid, salt, and acrylic paint. The group stated the chemical mixture was intended to corrode concrete and accelerate rusting in steel, though the actual structural impact on the facility remains unknown.

Extinction Rebellion framed the action as part of a broader campaign against AI infrastructure's environmental toll, arguing the facility exploits regulatory loopholes to bypass restrictions on hyperscale data centers in a region already facing power shortages. Spokesperson Martijn Dekker connected the protest to concerns over carbon emissions, local water consumption, and Microsoft's alleged role in supplying technology used in the conflict in Gaza.
