Well, there's the question -- I have no idea who owns it.  Look it up in 
ARIN, it says it's mine, but with contact info from epix, the old upstream. 
Again, though, even if I own it, if the announcements don't make it into the
backbone it's not very useful, and I gather that some backbones now filter at
/19 except for the swamp.

My ISP (the local independent telco who is quite sharp) is doing what 
they can but epix is less than helpful.
