In a new article published Monday, The Intercept has now revealed what it describes as secret AT&T facilities across several American cities that are “central to an NSA spying initiative.”

The piece builds on earlier reporting that the website did in November 2016 which focused on one such site in New York City.

The eight locations, which are in Atlanta, Chicago, Dallas, Los Angeles, New York City, San Francisco, Seattle, and Washington, DC, are “peering” facilities that normally route other telecom companies’ data traffic onto their network as part of their regular Internet service.
