+1 on this. We moved from an all anycast resolver setup to an anycast+dnsdist, resolver backend setup the way Bert described it. I would add that with dnsdist and caching enabled you don't need as many backend resolvers. 90% of the queries can be answered from dnsdist caches. So in our case, we have multiple dnsdist instances across the swiss NREN network but only few backend resolvers.
