I just run my own name server. DNS blocking is no longer an issue unless they get to the root name servers. With a little domain warming from the top 5000 domains it’s pretty snappy most of the time.
More realistically, DNS blocking is no longer an issue unless "they" get to the registries for the top-level/second-level domains.
