Dunno the exact number of hops but it's always long but I only have 1 WISP so I don't have a choice. It goes from my laptop to my home broadband router to my radio & antenna on the roof to the WISP antenna and at that point it bounces a while within the WISP's network before exiting on some backbone on it's merry way to centos. The ONE STOP prior to centos.org is the last stop; but all other web sites work. So, my "assumption" is that Centos.org is blocking me. I didn't think about this when I first posted this thread, but then someone told me that they ran a traceroute and there was only ONE STOP after where it stopped for me, so, that's when the light bulb lit. Now, as to WHY they're blocking me - that I asked their webmaster by mail, earlier today. > You could try checking something like > http://multirbl.valli.org/ Nice site. I see blacklists, whitelists, Yellowlists, neutralized, and even not listed as reports, and ALL (even the not listed) came up with zero.
