Activists from the Dutch group Geef Tegengas entered the Microsoft data center construction site in Amsterdam on Friday, November 6, 2026. The Dutch news agency ANP reports that tens of people occupied the site on Plimsollweg, that they got in by climbing the fence with ladders and cutting a hole in it, and that riot police used batons and pepper spray to bring them under control. No work took place on the site that day, according to ANP.
Other details are less solid. A headcount of about 100 and a price tag of 1 billion euros appear in secondary coverage that we could not open or confirm. This post separates what ANP reported from what is only claimed. It is an attack-or-protest story about AI infrastructure, so we cover it as a rule, and we attribute each figure.
TL;DR: what is confirmed and what is not
| Question | Status |
|---|---|
| Did activists enter the site on November 6? | Confirmed by ANP: tens of activists occupied it |
| Who was behind it? | Confirmed by ANP: the action group Geef Tegengas |
| How did they get in? | ANP: ladders over the fence and a hole cut in it |
| Were there police and force? | ANP: a reporter saw riot police use batons and pepper spray |
| Was the gathering banned? | ANP: the mayor had banned it |
| How many were inside? | Disputed. ANP: tens, with about thirty outside the fence. A Reuters figure of about 100 is relayed by search summaries only |
| Did work stop? | ANP: no work took place on the site that Friday |
| Is the site worth 1 billion euros? | Unconfirmed. We found it in one aggregator only |
| Will the site use as much power as all Amsterdam homes? | A claim by the activists, not verified |

What did ANP report?
ANP, via a republished wire report, says tens of activists took over the construction site of the Microsoft data center on Plimsollweg. About thirty stayed outside the fence when the riot police, known in Dutch as the ME, moved in.
The agency adds these details:
- The activists climbed the fence with ladders and cut a hole in it.
- The mayor had banned the action, and police were present in large numbers.
- A reporter saw the riot police use batons and pepper spray.
- Activists hung a banner from the scaffolding and the crane. ANP quotes its text as "down with datacentre, fuck AI."
- They also sprayed slogans on the concrete foundations.
- No work took place at the site that Friday.
- Dozens of activists had also occupied and blocked the site in June 2026.
ANP does not spell out a list of demands. The banner is the closest statement of intent we could read, and it opposes both data centers and AI as such.
What do other outlets add, and how reliable is it?
A set of English-language outlets covered the event the same day. We could read only a summary of their reporting through a web search, since several pages blocked automated access. We list them so you can check them, not as confirmation of every figure.
- The Next Web reported that protesters broke into the site. Search summaries say it reported multiple arrests.
- Search summaries credit Reuters with a figure of about 100 people on the site, which differs from ANP's "tens."
- The activists reportedly claim the data center could use as much electricity as all Amsterdam households combined, and describe the day as part of coordinated actions against data centers in Europe on November 6 and 7.
We did not verify the electricity claim against a Microsoft statement, a grid operator figure or a planning document. Treat it as the protesters' framing. If Microsoft or the grid operator publishes the planned capacity, that is the number to use.
How does this fit the earlier protests at the site?
ANP says dozens of activists blocked the site in June 2026. Trade outlets also reported that Extinction Rebellion threw acid-filled balloons at a Microsoft-linked data center site in Amsterdam's port area on July 17, 2026, a separate incident in which, per those reports, the activists stayed outside the fence. Those trade reports were summaries we could not open, so the July details are attributed, not confirmed.
The pattern is escalation in tactics at one location: a blockade in June, a chemical attack from outside the fence in July, and now an entry onto the site with riot police and a mayoral ban. The site is a recurring target, and this is the first of the three actions in which, per ANP, riot police used force.
Why data centers are now a protest target
AI demand has pushed data centers from an invisible utility to a local fight over power, water and land. Our recent coverage shows how wide the backlash is:
- In India, protests in Thane over a 22-hectare Amazon site centered on water and power.
- In Finland, Google's Kajaani site was halted over an environmental assessment law.
- In the US, Ohio voters passed data center bans in 14 municipalities on election day, and the midterm data center pipeline may be at risk.
- In China, local anger around Shaoguan data centers was reported by the FT.
Most of these fights are legal and political: votes, permits, moratoria. The Amsterdam action is different because it is direct action on a live construction site. That matters for security planning, insurance and project schedules, even when the protest itself is small.
What it means for builders and operators
If you build on cloud capacity in Europe, a single protest rarely changes your service. A few points are worth noting.
- Schedule risk is real but local. A day of halted work delays one site, and capacity planning for 2027 and 2028 already includes such slips. Watch for formal delays, not headlines.
- Power is the common thread. Protesters, regulators and voters keep returning to electricity use. Operators that publish planned megawatts and sources gain credibility. Those that sign non-disclosure agreements lose it. See how Amazon dropped data center NDAs in response.
- Security spending will rise. Construction sites with fences are soft targets. Expect more guards, cameras and legal action against trespass.
- Watch the claim-versus-fact gap. Numbers on both sides of a protest, like power use or site cost, are often unsourced. Ask for a primary figure.
For teams that run AI agents in these environments, the broader security lesson applies to digital sites too: control what can reach your systems before something goes wrong. AgentBeam, the agent security platform from the explainx.ai team, stops AI agents before they take dangerous actions.
Why headcounts and costs differ between outlets
Protest numbers are among the least reliable figures in news. They shift for ordinary reasons, and none of them needs bad faith.
A crowd is counted at different moments. The ANP report separates people who got through the fence from about thirty who stayed outside when the riot police arrived. A wire service that counts "tens" inside and an agency that counts "about 100" may be counting different groups: those who entered, those who gathered, or everyone who took part at any point in the day. Without the definition, the two numbers cannot be compared.
Cost figures behave the same way. A project value such as one billion euros can mean the building, the building plus equipment, or a multi-year commitment. Until a company filing or press release states the figure and what it covers, repeating it adds nothing. That is why this post lists it as unconfirmed.
Power comparisons are the weakest of all. Saying a site "could use as much electricity as all households in a city" mixes a design maximum with an average household load. The comparison is easy to quote and hard to check. A grid operator's connection capacity, stated in megawatts and phased by year, is the number that settles the question.
When you read the next protest story about a data center, look for three things: who counted, what was counted, and whether a primary source such as the police, the municipality or the company stands behind the number.
What is still open
- The exact number of people on the site, and the number arrested.
- Whether Microsoft or the site developer will comment, and whether they will press charges.
- Whether the planned power draw will be published, which would settle the electricity claim.
- Whether the coordinated actions on November 6 and 7 in other European cities escalate or stay peaceful.
- Whether the mayor's ban leads to fines or prosecutions.
How to check this yourself
- Read the ANP report and compare its headcount with Reuters and Dutch outlets.
- Search for statements from the Amsterdam police and the municipality on arrests and the ban.
- Look for Microsoft's or the developer's statement on site security and schedule.
- For power claims, look for the grid operator's connection capacity for the site, not the protesters' comparison.
- Treat any single-source cost figure, such as the one billion euros, as unverified until a filing or company statement appears.
