Once you've documented where the issue is, call your ISP and let
them
deal with it because that's what you're paying them for.
One thing which is strange for me is that another box running FC7 in
the same internet line can access the site. It is an indication of
no need to call ISP as the problem is in the side of my box.
Please be available to give more suggestions.
Thanks in advance.
