One way to achieve this is to have two nameserver and balance them behind dnsdist with the default 'leastOutstanding' policy. This means that as your server heats up its cache, it will only progressively get more traffic. This provides good end-user experience. http://dnsdist.org/ Preloading a cache has been considered by various implementations and generally causes more downtime/delay than heating up the cache to the point it has all relevant entries.
