3 weeks is plenty for a service that in 6 months you may see degraded to = 12/13 capacity if you haven't properly maintained it AND it is used for = recursive service. (trusting a referral from a root or sub-root = delegation to the root is crazy!).
3 weeks is not a lot of time to inform every recursive service operator in the world that there is a change coming. Remember nameservers will start logging warning messages as of January 3rd. There is a big difference between 'This is just fallout from D changing it's address' to 'What does this message mean and do I have to worry?'
I could only wish my automobile would notify me 6 months of its = impending failure should I take no action...
