Ken,

I do have an allow line for you

allow   DDPLUS|HRS|IDS|DIFAX    ^shadow.agry.purdue.edu$

Here's what it looks like from my end in my ldmd.log:

A traceroute looks like:

so it looks clean.

Maybe try changing your request line to 'sunset.aos.wisc.edu'. I did
make a change to our dns on Monday that results in reverse
name lookups returning the aos.wisc.edu domain instead of
meteor.wisc.edu, in anticipation of eventually dropping the
meteor.wisc.edu all together, but I didn't think that would
impact data requests. I haven't heard anything adverse from
anyone else..
