CHANDLER, AZ — A nonstop noise has a Chandler community demanding change. Neighbors say they cannot sleep or enjoy any peace or quiet because of a nearby data center.

People living near Dobson and Queen Creek roads say the CyrusOne facility has been producing a loud buzz at all hours for more than two years.

Neighbors say despite promises of peace, the loud hum persists.

“I would describe it as a blender on steroids, but at a distance,” said Bob Diepenbrock, who lives in the nearby neighborhood. “It’s the same volume, it’s the same tone, and it is a known issue,” said Diepenbrock.

Monday night, Diepenbrock and his neighbors petitioned the City Council to do something to address the noise.

“In the past two and a half years, I can honestly say I’ve not slept a full night's sleep,” said Cheryl Jannuzzi, who lives right by the facility.

CyrusOne told the city they addressed the noise in November on 24 of their chillers, which cause the noise, but neighbors say the noise hasn’t changed.

“I haven’t noticed a difference,” said Diepenbock. “Inside the house, we have to have a TV on, or music, in order to drown it out,” said Jannuzzi.

Chandler’s Mayor said he is going to write a letter to CyrusOne. He also wants city officials to tour the facility to ensure they’re making an effort with sound attenuation.

The neighbors say that is a start, but they will not stop until they can enjoy their backyards in peace.

The City Council said they may explore enforcing its noise ordinance, but want to give the company a chance to make changes on their own.

CyrusOne released the following statement about the issue:

"CyrusOne is committed to being a good neighbor and member of the Chandler community. While we continue to be in compliance with the City of Chandler’s ordinances, we speak with the City of Chandler regularly to discuss ways to attenuate the issue. After extensive testing and engineering reviews, we have started the process of installing sound attenuation packages on all the currently installed AC systems. This effort is ongoing and CyrusOne is committed to keep towards this goal in 2019 and beyond. This approach has been deployed successfully in other markets."
