I found some information related to this problem at http://www.ventanazul.com/webzine/articles/cannot-access-websites-ubuntu-gutsy-gibbon
I followed the instrutions: 1. sudo vi /etc/sysctl.conf 2. add this lines net.ipv4.tcp_wmem = 4096 16384 131072 net.ipv4.tcp_rmem = 4096 87380 174760 3. execute sudo sysctl -p Now it works just fine at my desktop. The problem is that this site is public so the clients who access this site don't have this solution. It should be a global fix for this problem.
