illicit above.net announcements?

[Kai Schlichting]

Anyone here who is on the Vienna/London/Amsterdam exchange(s) and
who is seeing what is alleged here: above.net leaking and/or
flapping routes that are not their own ?

Is there a lookingglass at any of these exchanges that is publicly
accessible?

bye,Kai
