NSA's Partnership with AT&T

There's a new article, published jointly by The New York Times and ProPublica, aboutNSA's longstanding relationship with AT&T. It's based on the Snowden documents, and there are a bunch of new pages published.

AT&T's cooperation has involved a broad range of classified activities, according to the documents, which date from 2003 to 2013. AT&T has given the N.S.A. access, through several methods covered under different legal rules, to billions of emails as they have flowed across its domestic networks. It provided technical assistance in carrying out a secret court order permitting the wiretapping of all Internet communications at the United Nations headquarters, a customer of AT&T.

[...] In 2011, AT&T began handing over 1.1 billion domestic cellphone calling records a day to the N.S.A. after "a push to get this flow operational prior to the 10th anniversary of 9/11," according to an internal agency newsletter. This revelation is striking because after Mr. Snowden disclosed the program of collecting the records of Americans' phone calls, intelligence officials told reporters that, for technical reasons, it consisted mostly of landline phone records.

Lots of details in the article and in the documents. Here's commentary from the EFF.

EDITED TO ADD (8/16): ProPublica has published a companion piece showing how they linked both AT&T and Verizon with the NSA's codenames. And Marcy Wheeler has some good commentary.

More commenary.
