Interesting, what is _really_ going on with the website?

I was having connectivity issues to www.freebsd.org from linux, netbsd 
and freebsd machines.  After adjusting  the appropriate value for linux, 
netbsd and freebsd the issues seem to clear.

Under linux adjust:

net.ipv4.tcp_window_scaling

Under FreeBSD/NetBSD adjust:

net.inet.tcp.rfc1323
