Martin, it occurred to me this morning that you are getting a ddos 
attack on your Tier-1 server, which are usually immune to this sort of 
thing.  I did a quick check and noticed that you are resolving recursive 
lookups, which is the reason why you are being flooded. Tier-1 servers 
should NOT resolve recursively for this very reason. If you turn off 
recursion, you should find that the attacks mostly go away within a few 
days.
