Amazon
5 entries · 3 in active litigation
Amazon appears in more entries on our tracker than any other operator: a $20.5 million nitrate settlement in Oregon, a homeowner's well and noise suit in Louisa County, Virginia, a three year permit fight in Warrenton, a federal ruling that sent a $4 billion Ohio campus back to square one, and the Great Oak noise dispute that ended without a suit. The full record, with status, sourced.

Meta
1 entry · 1 in active litigation
Meta's Stanton Springs campus in Newton County, Georgia produced the most widely reported data center water complaints in the country and, in late August 2026, a lawsuit by four families. In Cheyenne, Wyoming, a Meta contractor was identified as the source of a bacterium that contaminated the city's reuse water system. Meta builds in more contested states than almost anyone: Georgia, Louisiana, Indiana, New Mexico, Idaho, Utah, Nebraska, and Wyoming. The record, with status.

Microsoft
1 entry · 1 in active litigation
Microsoft faces the first noise class action ever filed against a hyperscale AI data center: three Sturtevant, Wisconsin residents sued in July 2026 over the 1.2 million square foot Fairwater campus in Mount Pleasant, seeking to represent more than 1,000 households within 1.5 miles. Microsoft has acknowledged a tonal humming sound from the cooling fans. The case, the company's wider footprint, and what it means.
- Active litigation: The Microsoft Fairwater Noise Class Action
xAI
2 entries · 2 in active litigation
xAI's Colossus data centers in Memphis and Southaven are the subject of two federal lawsuits over the same gas turbines: the NAACP's Clean Air Act citizen suit over unpermitted operation, with the Justice Department intervening on xAI's side, and a proposed class action by more than 10,000 Southaven residents over the noise. The full record, sourced.
- Active litigation: NAACP v. xAI
- Active litigation: Haley v. xAI
Google
1 entry
No neighbor has sued Google over a data center on our tracker. The case that involves it most directly is The Dalles v. The Oregonian, in which a city sued a newspaper to keep Google's water use secret and lost: the records showed the company using roughly 29 percent of the city's water. Google's footprint runs through Oregon, Nebraska, North Carolina, Alabama, and Virginia, and it withdrew from a contested Indiana site. The record, sourced.
- Settled: The Dalles v. The Oregonian
OpenAI and Oracle
1 entry
The OpenAI and Oracle campus in Saline Township, Michigan got built because the developer sued. After the township denied the rezoning, Related Digital filed an exclusionary zoning suit and the township settled by consent judgment, allowing a campus reported at $16 billion to proceed with a community benefits package. Residents say the settlement overrode their vote. With the Stargate project in Abilene, Texas, it is the record of the OpenAI build-out so far.
- Settled: Saline Township v. the $7 Billion Data Center
QTS and Compass Datacenters
1 entry
QTS and Compass Datacenters were the developers behind the Prince William Digital Gateway, more than 22 million square feet on roughly 2,000 acres beside the Manassas battlefield. Residents and preservationists sued over the rezoning in January 2024, a judge voided it in August 2025 for defective public notice, the Court of Appeals affirmed in March 2026, Compass dropped its appeal in April, and QTS withdrew its final appeal on July 2, 2026 and terminated the project. The record.
- Plaintiff win: The Prince William Digital Gateway Lawsuit
Vantage Data Centers
1 entry · 1 in active litigation
Two pending Wisconsin lawsuits target the Vantage data center campus in Port Washington: Sierra Club v. Wisconsin DNR over a reversal on environmental review, and an open meetings suit against the Common Council over closed-door developer agreement talks. Neither names Vantage as a defendant, and Vantage says it worked transparently with regulators. The full record, sourced.
- Active litigation: The Port Washington Lawsuits

Digi Power X
1 entry · 1 in active litigation
Digi Power X, the Miami company that turned a defunct North Tonawanda, New York gas peaker plant into a bitcoin mine and is now converting it to AI computing, faces a federal class action covering everyone within three miles.

- Active litigation: Valenzuela v. Alliance Cloud Services
Related Digital
1 entry
Related Digital is the data center platform of Related Companies, headquartered in Dallas. It is on the tracker for one case, and it filed that case itself: after Saline Township, Michigan denied the rezoning for its OpenAI and Oracle campus in September 2025, Related Digital and the landowners sued the township for exclusionary zoning, and the township settled. The record, and what the company says about the project.
- Settled: Saline Township v. the $7 Billion Data Center
Nebius
2 entries · 1 in active litigation
Nebius is an Amsterdam based AI cloud company listed on Nasdaq as NBIS, and it operates the 2.6 million square foot campus in Vineland, New Jersey at the center of the state's first data center noise class action.

- Active litigation: Independence, Missouri
Tenaska
1 entry
Tenaska is a privately held energy company headquartered in Omaha that manages a 6,622 megawatt generating fleet. In Nebraska it optioned 1,354 acres in Cass County for a proposed natural gas plant and data center with Google, and residents answered with a twelve month county moratorium and an outright village ban. No lawsuit has been filed, and that is what makes the record worth reading.
- Dispute, no suit filed: Cass County, Nebraska Paused Data Centers and a Village Banned Them Outright. No Lawsuit Was Filed, and That Is the Point.

1 entry · 1 in active litigation
Powerhouse Hillwood Holding, HW Technology Park Development, and American Real Estate Partners are the developers of the Joliet Technology Center, a 795 acre, 1.8 gigawatt campus valued at $20 billion. Residents sued in May 2026 to void the rezoning, alleging the public notice never said data center. The developers say the notice was adequate and no one asked to cross examine. The record.
- Active litigation: The Joliet Technology Center Lawsuit
CyrusOne
1 entry
CyrusOne is a colocation operator, not a hyperscaler, and it has generated more documented noise conflict than most companies its size. Years of complaints about the hum from its Chandler, Arizona campus produced mitigation in 2018 and then the first data center noise ordinance in the country. In Aurora, Illinois, complaints began the month it opened and the city answered with property line decibel limits. In Sangamon County, a 600 megawatt campus cleared the county board 17 to 10. The record, sourced.
- Dispute, no suit filed: Sangamon County Approved a 600 Megawatt CyrusOne Campus as a Conditional Use in a Farm Zone, on a Grain Elevator Analogy
EdgeConneX
1 entry
EdgeConneX is not a hyperscaler, and its biggest American dispute is not a damages case. It is a fight over whether the roughly 1,700 residents of Ashville, Ohio get to vote on the village's data center agreement with the company. After Ashville's fiscal officer rejected a referendum petition carrying 669 verified signatures, the Ohio Supreme Court ordered it certified on August 7, 2026. The record, sourced.
- Plaintiff win: Ashville, Ohio Put a Data Center Deal on the Ballot. The Ohio Supreme Court Made It Possible by Reading One Paragraph.
