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 ?

Taking the first of the netblocks mentioned, I see it as a /16 over LINX 
from above.net:

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

LINX has one:
