What is dig doing?  Are you sure it isn't asking for an A record?

If you drop the +trace option and "dig toggle.www.ms.akadns.net aaaa" 
the response is "normal."  No error and an answer section of just two 
CNAME records.

If you ask for A records, you get A records in addition to the CNAME records.

Nothing surprising...

As with IPv6, the problem with the deployment of frictionless surfaces is
that they're not getting traction.
