I am unable to access 1sttix.org from any device (phone/computer - hard wired or wifi) when connected to Cox internet at home. I can access it from my phone plan (verizon) I tried customer support who had me reset system but still does not work.

Just saw the traceroute, you are able to ping all the way through, so the web server you are accessing is blocking your access. That's the ONLY thing that can cause what's taking place. The traceroute shows you get ALL the way through. 

FYI, you should not copy the 1st 2 hops, and that includes your WAN IP and you don't want to broadcast that.
