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.
