Odd behavior from p4-0-0.MAR1.Austin-TX.us.xo.net

This should be corrected now.  I still cannot ping the host in question but
I am guessing that spamhaus has ICMP filters on their stuff.  It is
definitely routing to the correct place now.  Our customer service
department is following up with the customer (spamhaus' provider) to make
sure they are seeing everything correctly.
