Assuming that 61.9.128.250 is between you and me, and between you and contribs here's what I've found.
From my IP in the UK I get:

Now, when I go to
www.dnsstuff.com and use their tracert and ping utilities I can get to
www.contribs.org - but I can't get to 61.9.128.250

So, my diagnosis is that there is a problem somewhere in Telstra. You need to get hold of a good engineer at Telstra who'll listen and who is interested in fixing this problem.
From the UK I arrive at 10GigabitEthernet13-0.chw-core2.Sydney.telstra.net and get correctly routed on, from the
www.dnsstuff.com site I get to 10GigabitEthernet13-0.chw-core2.Sydney.telstra.net and get lost.
HTH - Good Luck!
David.
