Paging Ultradns/neustar neteng

UltraDNS / Neustar netengs :

  There is a routing instability in one view of a small part of your network
that¹s none the less making my phone blow up. (pdns4)

  Your noc guys didn¹t exactly get what I was trying to explain ; refer to
SR 1-48803905 for some data.

  An off-list ack would be cool in any case; I have an unrelated curiosity
or two I¹d like to throw at some neustar clue.
