We have seen issues like this also when a customer was leaking full 
routes, and his router ws not able to coop with the BGP tables. This gave 
really really strange things, simmilar like here, some prefixes were 
there and some not. Completely random.

Upstreams should filter things properly. Thats a sure thing. OR max prefix 
limit customers like that....
