reachability issue with 3ffe:80a::/32 (PAIX IX segment)

So, I said:

and. of course, I got it flipped around; traceroute from networks not
connected to the IX will report properly when tracing paths through
the IX, but networks not connected can't traceroute directly to an IX
address if its prefix is not propagated by the connected providers.
