It's not just you, I'm experiencing the same from both a FreeBSD and an 
Ubuntu host on dramatically different networks (one in LA, one in 
Omaha). What's more interesting to me is that 'ping www.xbox.com' works, 
as does 'ping6 www.yahoo.com' which has just as many CNAMEs in its chain 
(albeit they are not going to Akamai).

weird,

Doug
