Whoa.  You've given two different and distinct sites:
david at alanje:~$ dig +short myloweslife.com
168.244.164.134
david at alanje:~$ dig +short www.myloweslife.com
168.244.164.81

So where do you really need to go?
david at alanje:~$ tcptraceroute www.myloweslife.com

Well, that's telling.

So trace and ping don't work, but a connection does -- to
WWW.myloweslife.com. I have not tried the myloweslife.com site (which has a
different IP).

The "baseline" I mentioned is just knowing the hops/hopcount to wherever
you're going.

Hope that helps,

David A. Bandel
