Re: illicit above.net announcements?

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:

rt2-thdo#sh ip bgp 202.36.147.0
BGP routing table entry for 202.36.0.0/16, version 11913196
Paths: (5 available, best #1)
  Advertised to peer-groups:

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

LINX has one:
