You might ask them if they'd mind adding that (the data is there for
people to look at after all).  Otherwise, all you really need to do is
to look for the links to rib.<foo>.bz2 and sort (they are zero padding,
so a simple lexical sort will work).  You'll have to deal with the
directory name as well though.

Or, you could cheat, and just try to download what would be the latest
file (they are .../YYYY.MM/RIBS/rib.YYYYMMDD.HH00.bz2 where HH is even
and the times are UTC) and just count backwards until you get a hit (or
limit it to one day's worth of tries).

Fair enough.  I come at problems from an ISP approach; I've got a number
of servers running BGP, OSPF, or both in my network. :-)

I don't speak for anybody but myself - that's enough trouble.
