not responding when accessing a certain URL to 'port upgrade'

[Kuniaki Mukai]

Hi,

There are URLs which start with "http://ftp.nara.wide.ad.jp/pub/X11/GNOME/sources/ 
"
such that "port upgrade" never proceed beyond fetching any of the  
URLs, like
the following, whenever I try at my home.

% sudo port upgrade  libgsf
Password:
--->  Fetching glib2
--->  Attempting to fetch glib-2.20.2.tar.bz2 from http://ftp.nara.wide.ad.jp/pub/X11/GNOME/sources/glib/2.20/
(not responding)

The urls "http://ftp.nara.wide.ad.jp/pub/X11/GNOME/sources/..."  are
only such exceptions as far as I notice.

However, there is no such troubles whenever I do 'port upgrade' at my  
office.

Thank you for any hints on how to fix this trouble.
