[CentOS] Strange connectivity problem from linux.

Hi I have been facing a strange connectivity problem from CentOS and
Fedora boxes.

When I telnet to
$ telnet adp.eease.com 443

it works fine some times and every 5-10 tries or so it says connection
refused. And this does not happen from my windows box.

Can anyone from this list try this on their linux installation and see
if they get the same behaviour?

Thanks
Tharun
