Default OT: How can I tell if a web site is now blocking IPs frommy country?

Try using a few traceroute servers to see if other IP addresses
from Colombia other countries are able to get to them.

Other than that, I don't think you can tell from the
outside.

Neil: Thank you! I didn't know trace route servers existed. From the
below, it looks to me as if there may be a problem, at the router
past the last one I was able to get to, since the University of
Maryland and Careleton University trace route servers also got stuck,
just past where I got stuck. Possibly it's intermittent, since the
site is showing "up" and I was able to get to it, using an Anonymous
Web Browser. Snow in Houston? :-) Lanny

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
