I'm getting lots of queries to our resolvers for various names under
aws.blueapron.com, which all lead to

dcos-pub-east.aws.blueapron.com. 60 IN CNAME dcos-pub-east.aws.blueapron.com.

and thus an obvious CNAME loop, with our BIND resolvers logging messages
about "query iterations limit reached". So far so good. I'm wondering if
this is on purpose (trying for name server resource exhaustion) or some
kind of mistake. Anybody else seeing this?
