Klaus, this was discussed at the last RIPE meeting. What a country  
does with its ENUM name servers is a National Matter. This is not  
something that RIPE NCC should interfere with and it must NEVER pull  
an ENUM delegation unilaterally. A delegation under e164.arpa should  
only get deleted by the NCC -- not RIPE! -- if instructed to do so by  
the ITU or the appropriate Administration. Read the IAB instructions  
and ITU MoU to the NCC for details of the scope of NCC's ENUM  
responsibilities.

What we -- for some definition of "we" -- should do in this situation  
is inform the Administration concerned and politely ask them to fix  
the problem. IMO this definition of "we" means you and the ITSPs who  
are having trouble. It doesn't mean RIPE NCC unless the relevant  
Administration has asked the NCC to monitor their ENUM delegation.

If that's the case, perhaps ITSPs should reconfigure their software  
until the DNS infrastructure for this domain is reliable enough.
