Protesters Storm Microsoft Data Centre Site in Amsterdam as Police Detain Up to 200 in Europe-Wide Backlash Against AI Facilities

Protesters broke into the construction site of a planned Microsoft data centre in Amsterdam on Friday, November 6, 2026, climbing a crane, setting off flares and clashing with police in one of the most dramatic actions yet against the spread of large data centres in Europe. Dutch police said that by Friday evening they had detained between 150 and 200 people on suspicion of trespassing, after riot police moved in to clear the site in the city’s western port area. The protest was organised by the Dutch direct action group Geef Tegengas, and it formed part of a two-day campaign by the Stop Dirty Data Centres coalition, with demonstrations planned in 15 or 16 countries across Europe. The demonstrators say the giant facilities built to power artificial intelligence consume too much electricity and water and serve clients they oppose. Microsoft said it was aware of the demonstration and respects peaceful expression but does not condone unlawful entry to the site. The events in Amsterdam are the Microsoft Amsterdam data centre protest November 2026, and they show how far the backlash against AI infrastructure has moved from argument into direct action.

1. What happened on Friday in Amsterdam

The protest began as a march and ended as an occupation. Demonstrators set out for the construction site in the morning, were stopped by police before they arrived, and then broke through the site’s boundaries in groups. By the afternoon, protesters were on cranes and silos, banners were hanging from the structures, and riot police were escorting people off the grounds. The day ended with large numbers of detentions and with the site still at the centre of a dispute over whether it should be built at all.

1.1 The break-in at the Plimsollweg site

Two groups entered the site by cutting open a gate, according to a police statement reported by Bloomberg, and a Reuters witness counted about 100 people breaching the site’s boundaries. Other reports described around 200 activists in blue overalls cutting through fences with concrete shears at the Plimsollweg site in the Westelijk Havengebied, the western port area near the Sloterdijk district. Once inside, some protesters climbed a construction crane and a silo and set off flares, while others sprayed graffiti and hung banners, including one reading “Screw your datacentre”. The organisers said on social media that hundreds of activists had blocked construction of the data centre. The site is a campus being built by the British developer Pure Data Centres, and it was, by Friday, a construction zone of towers, cranes and fencing rather than a finished building.

1.2 Police response and detentions

Police had halted the march as it approached the site on Friday morning, and the mayor then banned the gathering, according to Dutch news agency ANP. When protesters tried to break through police barricades, officers moved in, and by late afternoon riot police were escorting people off the site, although some protesters still remained, local media reported. Police said force was used and an officer was slightly injured, while protesters told the Guardian that police used force and tear gas. A separate group marching from Sloterdijk train station was stopped and searched by police before reaching the site. By Friday evening, police said they had detained between 150 and 200 people on suspicion of trespassing. Earlier reports during the action had put the figure far lower, at one arrest, with police confiscating an angle grinder and climbing equipment, which shows how quickly the picture changed as the day went on.

2. The site at the centre of the protest

The Amsterdam site is not a small server room. It is a large campus of three tall towers planned for the city’s western port area, and it is designed to serve a single tenant. Its scale is central to the dispute: critics say a facility of this size will place heavy demands on the electricity grid and on water supplies, while the developers and the city say the project went through the proper planning process. The numbers attached to the project explain why it became a target.

2.1 Three towers in the western port area

The campus, known as AMS01, is being built by Pure Data Centres in Westpoort, Amsterdam’s western port area, on Plimsollweg near Sloterdijk. It comprises three buildings, each standing 85 metres tall, and it has a planned capacity of 78 megawatts, according to reports of the project. The project is worth about one billion euros, according to Dutch broadcaster NH Nieuws, and it is due for completion in 2028. Pure Data Centres is backed by Brookfield-owned Oaktree, which has committed more than one billion dollars to the facility, according to reporting on the project. The site was already contested before Friday: since 2022, national rules in the Netherlands have limited new hyperscale data centres to two locations, Eemshaven and Wieringermeer, and campaigners argue that Amsterdam should not be hosting a facility of this scale.

2.2 Microsoft as sole tenant

Microsoft is reported to be the campus’s sole tenant, although Pure Data Centres’ own project page confirms only that the campus is fully leased. That distinction matters, because the protest was aimed at Microsoft as much as at the building itself. Some of the demonstrators objected to Microsoft’s services to the Israeli military and to United States Immigration and Customs Enforcement, the Guardian reported, while others focused on the environmental cost of the data centre. The company is one of the largest builders and buyers of data centre capacity in the world, as the artificial intelligence boom drives demand for computing power. For the protesters, a site leased entirely to Microsoft made Amsterdam a visible place to challenge that expansion, and the company’s name on the project is what turned a local planning dispute into an international news story.

3. Who organised the protest and why

The Amsterdam action was not spontaneous. It was organised by a Dutch direct action group, supported by climate campaigners and pro-Palestinian activists, and timed to coincide with a coordinated European campaign. The groups involved share a view that data centres are a climate and social problem, not only a technology story. Their arguments reach beyond Amsterdam, and they have been building for months as data centre construction has spread across the continent.

3.1 Geef Tegengas and its allies

The protest was organised by Geef Tegengas, a Dutch direct action group whose name translates as Push Back, according to reporting by NL Times citing local broadcaster AT5. Nathan Timmer of the group told AT5 that protesters were occupying the site in an effort to stop construction. Extinction Rebellion and pro-Palestinian activists joined the action, while Fossielvrij NL, also known as Fossil Free Netherlands, demonstrated at the site but not on it. Danish activists also took part, according to reports of the day. A campaigner with Fossil Free Netherlands told Bloomberg that an estimated 400 protesters participated in the demonstration. The mix of groups shows how the campaign against data centres has drawn together climate activists, digital rights campaigners and pro-Palestinian groups, each with its own reasons for opposing the project.

3.2 Energy, water and the AI boom

The core argument of the campaigners is that data centres, and especially the facilities built to train and run artificial intelligence systems, use enormous amounts of electricity and water. Critics argue that a single large campus can consume as much power as a whole town, and figures circulated by critics of the Amsterdam project compared its demand with the electricity use of homes across the city, a comparison that has not been independently verified. The planned capacity of 78 megawatts gives a sense of the scale: it is the power demand of a small town, concentrated in three towers on one site. Campaigners also point to the water used to cool servers and to the strain that new facilities place on grids that are already under pressure from the energy transition. Supporters of data centres argue that the facilities are essential infrastructure for the digital economy and that they can be run on renewable power, but the protesters in Amsterdam plainly do not accept that the benefits outweigh the costs.

4. The numbers in dispute

Almost every number attached to Friday’s protest is contested. The organisers, the police and the reporters on the ground gave different figures for how many people took part and how many were detained, and the gap between the accounts is wide. That is normal for a fast-moving protest, where counting is difficult and where each side has an interest in the figure that is reported. The honest account is to report each figure with its source and to say plainly where the figures disagree.

4.1 How many people took part

A Reuters witness counted about 100 people breaching the site’s boundaries, while a spokesperson for Geef Tegengas told AT5 that about 500 demonstrators entered the grounds, with hundreds more remaining outside. A campaigner with Fossil Free Netherlands put the total number of participants at an estimated 400. Other reporting described around 200 activists taking part in the break-in itself. The differences reflect different ways of counting: the number who entered the site, the number who marched, and the number who were present in the area. What is not in dispute is that the demonstration involved several hundred people, that two groups cut through the gate and fences, and that the action was large enough to halt work on the site and to require a major police deployment.

4.2 How many were detained

The detention figures changed through the day. During the action, Bloomberg reported, citing a police statement, that at least one person had been arrested and that police had confiscated items including an angle grinder and climbing equipment. The Associated Press subsequently reported several arrests as riot police cleared the site. By Friday evening, the police figure was far higher: ANP, citing the police, reported that officers had arrested an estimated 150 to 200 demonstrators on suspicion of trespassing, and German agency dpa carried the same police announcement. The Guardian and other outlets reported the same 150 to 200 range. The figure is a police estimate of arrests, not a final count, and it was not clear on Friday night how many of those detained would face charges or how long they would be held.

5. A two-day campaign across Europe

The Amsterdam protest was one action in a much larger campaign. The Stop Dirty Data Centres coalition, which is calling for a moratorium on large data centres across Europe, organised two days of demonstrations on November 6 and 7, and the Amsterdam occupation was the most visible of them. The campaign reflects a growing movement that has moved from local planning objections to coordinated international action, and it has gathered pace as the artificial intelligence boom has driven a wave of new data centre construction.

5.1 Stop Dirty Data Centres

The coalition, Stop Dirty Data Centres, describes its aim as a halt to the construction of large data centres across Europe, and it organised the two days of action on November 6 and 7. The campaign brings together climate groups, digital rights organisations and local residents’ campaigns in several countries. Its argument is that the current pace of data centre construction is incompatible with climate targets and with the limits of electricity grids and water supplies. The coalition’s actions are deliberately timed and coordinated, so that protests in different countries happen on the same days and reinforce each other. Amsterdam was the most confrontational of the actions reported on the first day, but the organisers said the campaign would continue into the second day.

5.2 Protests in 15 or 16 countries

Reports differed on the scale of the campaign, with the number of countries involved put at 15 or 16 depending on the count. Demonstrations were expected in several European countries on Friday and Saturday, demanding a halt to large-scale data centre developments, according to Associated Press reporting. Danish activists joined the Amsterdam action itself, travelling to the Netherlands to take part. The spread of the campaign shows that opposition to data centres is no longer a local issue in one city or one country: it is becoming a European movement, with shared tactics, shared slogans and shared targets in the form of the largest technology companies. Whether that movement can sustain itself beyond a two-day action, and whether it can change planning decisions, remains to be seen.

6. The Dutch rules on hyperscale data centres

The legal background to the Amsterdam protest is a set of national rules that have limited where large data centres can be built in the Netherlands since 2022. Those rules were introduced because of concern about the pressure that hyperscale facilities place on the electricity grid and on land use. The Amsterdam project sits in a grey area of those rules, and the two sides disagree about whether it should have been allowed at all.

6.1 The 2022 limits on new sites

Since 2022, national rules in the Netherlands have limited new hyperscale data centres to two locations, Eemshaven and Wieringermeer. The policy was a response to the rapid growth of data centre construction and to the demands that the largest facilities make on power and space. The intention was to concentrate the biggest facilities in places where the grid and the land could cope with them, rather than allowing them to spread across the country. The Amsterdam campus, with three towers of 85 metres and a planned capacity of 78 megawatts, is large by any measure, and campaigners argue that a project of this scale should not have been permitted in the capital. The rules are part of a wider European debate about how to manage the growth of digital infrastructure.

6.2 The argument over this permit

The city’s position is different. Amsterdam alderman Steven van Weyenberg has said that the project was a single permit application and would not have counted as a hyperscale centre in any case, according to reporting on the dispute. That is the crux of the disagreement: whether the campus, taken as a whole, is a hyperscale facility that falls under the national limits, or a single permitted development that does not. The developer, Pure Data Centres, has continued building on the basis of its permit, and the project is due for completion in 2028. The protesters reject the city’s reading and want construction stopped. The dispute is now as much political as legal, and Friday’s action was an attempt to force it back onto the public agenda.

7. What Microsoft and the police said

Both Microsoft and the Dutch police issued statements during and after the protest, and their accounts differ in emphasis from the protesters’ account. Microsoft acknowledged the demonstration and defended the right to peaceful protest while condemning the unlawful entry. The police described a banned gathering, a breached site and a large number of detentions. Neither statement settles the argument, but both are part of the record of the day.

7.1 Microsoft’s response

Microsoft said it was aware of the Amsterdam demonstration. A spokesperson told Gizmodo in an emailed statement that the company respected peaceful expression but did not condone unlawful site entry, and Associated Press reporting said the company acknowledges the protest but condemns unlawful actions. The company did not, in the statements reported on Friday, address the protesters’ specific objections to its services to the Israeli military or to United States Immigration and Customs Enforcement, or their arguments about energy and water use. Its position, as reported, was a narrow one: peaceful protest is legitimate, breaking into a construction site is not. That leaves the substantive dispute about the data centre itself unanswered, and it is likely to be pressed again if the campaign continues.

7.2 The police account of the day

The police account, as reported by Dutch news agency ANP and by Bloomberg, is that officers blocked the march before it reached the site, that the mayor banned the gathering, and that two groups then cut open a gate and entered the grounds. Police said force was used and an officer was slightly injured. They confiscated an angle grinder and climbing equipment, and by the evening they reported detaining an estimated 150 to 200 people on suspicion of trespassing. The organisers accused the police of misconduct, saying the protesters’ right to demonstrate had been disregarded. Protesters told the Guardian that police used force and tear gas. The two accounts agree on the sequence of events but disagree on whether the police response was proportionate, and that disagreement is likely to be examined in the days ahead.

8. What remains unconfirmed and what to watch next

Much about Friday’s protest is still unconfirmed. The final number of detentions, the number of people charged, the condition of the injured officer, and the state of the construction site have not been finally established. The second day of the European campaign was still to come, and the longer-term future of the Amsterdam project is unresolved. What happens next will depend on the police, the courts, the city and the campaigners.

8.1 The final detention count and any charges

The figure of 150 to 200 detentions is a police estimate, not a final count, and the reports available on Friday did not establish how many of those detained would be charged or released. It is not yet confirmed whether the officer who was slightly injured needed hospital treatment, or whether any protesters were injured during the clearance of the site. It is also not confirmed how much damage was done to the site, to the crane and the silo that protesters climbed, or to the fences and gates that were cut. The police have not, in the reporting available so far, given a final account of the day, and the organisers’ claim that hundreds entered the site has not been independently verified.

8.2 The second day of protests and the project’s future

The Stop Dirty Data Centres campaign was planned for two days, November 6 and 7, so further demonstrations were expected on Saturday across Europe. Whether the Amsterdam site sees further action, and whether the city or the developer responds to the protest, remains to be seen. The project is due for completion in 2028, and construction has not been reported as halted beyond Friday’s disruption. The wider question is whether the Amsterdam action marks a turning point in the European backlash against data centres, or whether it remains a single dramatic day. The Microsoft Amsterdam data centre protest November 2026 will be judged by what follows it: by the charges, by the second day of protests, and by whether the project at Plimsollweg is built on schedule or becomes the first data centre stopped by direct action.
