akamai name servers have problems with EDNS requests. By default, bind
8.3.3 sends EDNS probes to name servers when starting a lookup sequence.
However, in my experience BIND 8.3.3 generally falls back to non-EDNS
queries and then everything is happy. The behavior you describe below is
quite odd.... are you 100% sure that you're running 8.3.3 on your
resolvers?  I ask because:

If you are using 9.2.0 by chance, you should definitely upgrade to 9.2.1.
