A minor clarification - ANS has never had or announced a route to net
1.0.0.0/8.  I'm not saying what you calimed to be doing wouldn't work.
You were probably verifying that PSI was announcing net 1 and had a
working default route to ANS.  At that point you should have received
!H in the traceroute.

The fact that you could rely on this anomoly also verifies the
consistency of PSI incompetence in configuring their routing.

BTW- You might try a traceroute to an address in 140.222/16.  That's
the ANS backbone.  For example, traceroute 140.222.32.62 would verify
that you could reach ANS NY POP.  Traceroute 140.222.1.1 would give
you a !H as soon as you reach an ANS interface (look for t3.ans.net in
the DNS if the response is not from a 140.222 address).
