www.heroesonline.com unresolvable via local unbound instance?

[Todd Blake]

My ISP is Spectrum (Charter) in the US, from what I can tell, they don't
seem to block much of anything, if anything, at all.

The "fairly common" comment was just a guess on my part as I've never had
to troubleshoot DNS like this.  I see no logical reason why I shouldn't be
able to contact their DNS servers.  I was just at a loss as to what the
issue might be.

Though I also noticed, that if I set my DNS to 8.8.8.8 on my desktop PC,
and can thusly resolve the domain, I still can't reach the website. This
smells less like intentional blocking, and more like maybe routing, or some
other misconfiguration at the host for the domain.
