DNS cleanup

• Not very glamorous
  
  
• Legacy network didn't implement authoritative-vs.-cache split
  
  
  • Want to guarantee performance of authoritative lookups by caching on separate hardware
    
    
  • Sometimes zones are moved w/o notice
    
    
• Doing it right first would have been better
  
  
  • Cleanup is slow, time-consuming
