Large FreeBSD installations/users?

[mhab12]

I'm about to build a large NAS (nas4free) for my HOA and thought it would be good preparation to know some names of larger users of FreeBSD for our upcoming meeting.  I remember this thread http://forum.pfsense.org/index.php/topic,7668.60.html but wondered if anyone knew of other Fortune 500 installations or major users of FreeBSD.  Doesn't necessarily need to be for file servers, routing or whatever else works as examples too.  Thanks.
