It is highly improbable that all these name servers are unreachable
from you. Therefore, I suspect that *content* is the issue. RIPE-NCC
zones are signed with DNSSEC. Are you sure you do not have a broken
middlebox which deletes DNSSEC-signed answers?
      
Ahem. dig's +trace doesn't use EDNS by default, so no signatures and
(usually) no large responses.
    

I actually suspect no IPv6 path rather than DNSSEC, add a -4 to force IPv4.
  

And that is the solution!


(and I upgraded the resolver on all the machines to 9.6.1-P1 before
getting that far.)


Thanks,
