THANKS to all of you great guys who have helped obtain data
on this problem!
Here are some results:
For 26 users in the US and Canada, I get 11 that worked OK,
and 14 that did not work. Of the 14 that did not work,
6 (including me) got stopped at cogentco.
It seems that users in other countries had no problem
(Sweden, Ireland, UK).
Thanks again for taking the time to help research!
Jon
