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.
