I recently got two domains, abc.com and xyz.com hosted with two
competlely different companies. I used wget to transfer files between
them for the past two weeks, but now I keep getting "Unable to connect
to remote host". The odd thing is this is true whether I use wget from
either domain. It appears wget has built in intelligence to
automatically 'ban' sites that it wget's too much from? All other sites
work fine, except my own?
