Ross: That's probably the first place I checked and it showed  that
web site was "up" and then I was able to access it, via an anonymous
web browser service. At first, I thought maybe they were blocking
Colombian IPs, or, that I had a problem with the Caching DNS in my
IPCop box, but, now, I believe there is a connectivity problem, in
Russia.  I will try to contact them, so they can troubleshoot the
networking problem.   Lanny
