Two administrative boo-boos?

I believe I've found two administrative boo-boos.

4 mae-east.enkido.net (198.32.187.119) [5696] 27.268 ms 23.847 ms 24.667 ms

Problem #1: The hop above is showing up for traces into an exodus.

I can find no reason why these would go through enkido.net on the way to 3967.


At first, I though this was just a typo in the an-addr records but, after consulting
http://www.mae.net/atm/east-addr.html the address is indeed enkido's mae-east connection.  Perhaps someone can explain
why I'm seeing this path.



Problem #2: It looks like Winstar is announcing EP space.
