So wait.  Teleglobe has OCCAID's route?  This is trace from Teleglobe to

OCCAID does not receive full transit from any network anymore.  They are
default free.  If there are missing prefixes, then OCCAID and the other
network need to work it out.

I would guess you would need to take this up with ARIN.  But yes, there is
something Teleglobe can do about this.  They can peer.

I don't believe it was 150 yesterday unless some additional network
peered/connected with OCCAID.  There was an additional peer added a week or
so ago, France Telecom.  Maybe this resolved some of the missing prefixes?

No, not at all.  However, OCCAID is available in enough common
points-of-presence to peer with OCCAID because it makes sense and this is
hurting Teleglobe's PAYING CUSTOMERS.

Half?  Now it's half?  Bernhard, please stick to your story.
