Equinix and Big 7??

The latest Cooke Report made the following statement: "They are, he says, the Internet Core Networks that announced anonymously on December 5, 2001 their decision to move their peering to Equinix Exchanges. He identifies them as UUNET, Sprint, Cable and Wireless, Genuity, Level 3, Qwest, and AT&T." I was wondering if anyone could verify these seven networks moving their collective peering to Equinix and if so any specifics. Previous posts in the archive on participants at Equinix do not seem to bear this out. Any feedback is greatly appreciated. Thanks, sean
