Protesters break into Microsoft's Amsterdam data center site

Members of the action group Geef Tegengas helped organize the protest. Around 100 people made it onto the construction site on the western edge of Amsterdam. Some climbed a crane to hang a banner. Others unfurled more banners and chanted slogans against Microsoft.

Some carried placards that said "Screw your data center." Several banners dealt with the war in Gaza, because some protesters object to Microsoft's contracts in Israel. Others were aimed at AI itself.

Pure Data Centres, the company building the site, answered quickly. "We respectfully ask those on site to leave safely and engage with us in dialogue about the development and any concerns they may have," it said.

Microsoft said it understands that people feel strongly. It said it respects the right to peaceful expression but does not condone unlawful action.

The site is a data center, a large building packed with computers that store data and run apps and AI tools. This one is for Microsoft alone. Microsoft is the only tenant, which means it rents the whole thing.

The project has three towers, each 85 meters tall. That is about the height of a 25-story building. Together they can draw 78 megawatts of power. Local reports say the three buildings will use about as much electricity as all the homes in the city of Haarlem put together.

The British developer Pure Data Centres is building it. Reports put the construction cost at about 1 billion euros. The first piles went into the ground in January 2026.

In real life Think of a data center as a giant, very busy library of computers. Every time you stream a show, back up photos or ask an AI a question, a machine in a building like this does the work.

Yes, and that is the heart of the anger. In late 2023 the city announced a pause on new data centers. It later said it would stop new ones until 2030. In 2022 the Dutch national government also decided that very large data centers belong only in two northern regions, Eemshaven and the Wieringermeer polder.

This project slipped through. The plans began as far back as 2016, before the bans. The city's pause did not cover six projects that were already far along, and this was one of them.

The developer also applied for three separate towers instead of one big center. The province of Noord-Holland judged each tower on its own. Tall towers use less land, which the province counted in the project's favor.

Some local lawmakers were furious that the permit came three years after the national rule on very large centers. Critics say the design found a loophole in the law. The developer and the authorities say the permits were granted properly.

The reasons come from two sources: what the protest group says, and what Dutch reports describe about the power grid.

The Stop Dirty Data Centres coalition lists many worries. They include rising energy bills, a shortage of housing, heat waves, water use and the effect of big tech on democracy. Some also point to privacy and surveillance. The group says it wants to "hold elected officials to account."

The power grid is a very practical worry. Amsterdam has had grid congestion since 2021, which means the electricity network is close to full. Local reports say the shortage could delay the building of up to 30,000 homes.

The Dutch government has limited the size of data centers in recent years, after provinces and cities complained about the strain on the electricity network. Data centers used 4.6% of all the electricity in the Netherlands in 2024. That is a big share for buildings that employ few people once they are running.

Another Amsterdam project shows the same tension. Residents of Zuidoost, a district in the southeast, started a campaign this summer against a different data center. More than 500 people have joined it, and they say it brings "zero benefits to the area."

The catch: A new data center takes a big slice of a grid that homes also need. That is the trade-off many Dutch officials now argue about.

No. This site has been a target all summer. On June 12, 2026, Geef Tegengas members occupied the site and chained themselves to structures. Dozens climbed cranes and construction halted for a time.

In mid-July, Extinction Rebellion threw water balloons over the fence. The group said they held hydrogen peroxide, acetic acid, salt and paint, a mix meant to eat at concrete and rust steel.

Pure Data Centres said it had not tested the liquid. It said that if the claims were true, the action was dangerous and could have hurt protesters or workers. It also said there was no damage and no delay, and that police were informed.

Extinction Rebellion said it planned similar actions at other data centers. Its spokesperson linked the fight against data centers to wider concerns about corporate power.

Friday's break-in was the first of a planned wave. The Stop Dirty Data Centres coalition says it is holding actions on November 6 and 7, 2026. A map on its site shows 85 locations in 16 countries.

Amsterdam, Dublin, Warsaw and another Microsoft site in Denmark are on the list. This week activists also staged a mock military checkpoint outside a Microsoft data center in Dublin.

The coalition's main demand is an immediate moratorium on large data centers in Europe. A moratorium is an official pause, with no new permits until rules are reviewed.

Europe is not alone. Data center opposition was a big theme in the US midterm elections this week, and voters backed limits on unchecked growth in many places. Microsoft also dropped the UK's largest data center project last month, after grid officials said the site would not get power until the 2030s.

AI needs a lot of computing, and computing needs buildings and power. Tech companies are building data centers at a record pace. Communities are now asking who pays for the electricity, the water and the land.

Other European governments are already acting. Denmark has paused new grid connection requests, which have passed 60 gigawatts in total. Google is facing a criminal probe over the clearing of 816 acres of forest in Finland, which the company's local arm allegedly cleared without a permit.

What's next: More protests are expected over the weekend, and the Amsterdam developer says it wants talks. Nothing reported so far says construction has stopped.

• Your AI tools run somewhere real. Chatbots and cloud apps depend on buildings that use large amounts of power and water.
• Local power matters. If you live near a planned data center, grid limits and permits can affect housing and your electricity prices.
• Expect more debate. Europe's pause calls and US voter pressure may slow some new projects.
• Rules are still shifting. Permits granted years ago, like this one, may not survive growing public pressure.
