Oddly enough, I'm having the same problem you have with mine, am on the same server (70.86.136.178), and other people with my ISP (optimum online) can access the site, even though they live right down the street from me. I've been to two live help sessions and neither of them have been able to figure out anything wrong that would cause this.
[Edit- I failed to mention I can't connect to your subdomain either.]
The only way I've been able to get to my domains/subdomain is by going through a proxy in Vietnam. Here's a tracert...

A friend of mine a few doors down gets the same path but correctly connects on the 17th hop.
