Well, that problem, as I see it, is that you just keep looking for it in 
the wrong place/direction.
As Mark (waldo kitty) already mentioned, a traceroute doesn't 
necessarily mean anything, the type of data for such scans(ICMP/IGMP) is 
a lot of times these days filtered along the way.

again, such traceroutes don't mean anything

I am working all over town (Los Angeles, that's a pretty big 
town!<LOL>), from roughly a dozen different locations, with almost 
always different ISPs (Verizon, AT&T, Time Warner, Time Warner Business, 
DSLExtreme, CBeyond,...) , types Internet connection (DSL, digital 
cable, FiOS, T1/ATM based, wireless broadband) and never had a problem 
reaching this site.

If you have tested from your own home/office location so far only, look 
in whatever firewall/router you have in place as the first possible 
culprit.  In an earlier post you showed the start of your traceroute,

which indicates that you double NAT'ed before you hit the first router 
in the Roadrunner/TWC infrastructure in Rochester, NY.
That makes two local devices that can possibly interfering. Unless you 
start looking into those, at the very least to eliminate them as the 
source for your problem, you can compare other people's traceroutes all 
you want, you still will be looking at the wrong end...
