On the following web page:
http://www.debian.org/CD/jigdo-cd/
Under Official Images, The USA mirror link points to:
http://us.cdimage.debian.org/jigdo-area/3.0_r2/jigdo/
The USA mirror times out when I try to access it (10060 - Connection timeout).
I can't tell if there is a server problem or if the network
is congested.
