Looks like this may be a cloudflare related issue; I'm just getting 
servfail responses across the board to my on-net resolvers from 
cloudflare (not using public dns services).

Sometimes I'll get two A records which do work instead of the CNAME, so 
login.authorize.net occasionally works if I get lucky. But the TTL is 
300 seconds to that luck doesn't last too long.
