Deleting a public hosted zone

Important

If you delete a hosted zone, you can't undelete it.
You must create a new hosted zone and update the name servers for your domain registration,
which can require up to 48 hours to take effect.

In addition, if you delete a hosted zone, '''someone could hijack the domain''' and 
route traffic to their own resources using your domain name. 

自分はおなじNS(群)を指定できないのに、他人は乗取れると言っている。:-)

• awsdnsの運用を直すつもりはなさそう。簡単な対応がある。
