Teredo sunset - did it happen?

ISTR that Teredo was going to be sunset, Microsoft having tested 
removing the DNS name "teredo.ipv6.microsoft.com".

(Ignoring the Xbox One stuff here - just the windows desktop 
server/relay stuff)

However, my Windows 7 machine is still resolving that name and forming a 
Teredo address, and setting an IPv6 default route via that tunnel - I 
can see Teredo-encap'd router-solicit and router-advert messages being 
sent and received.

No traffic flows however - the Teredo "direct connect" tests are all 
failing (no reply to the ICMPv6 echo). So I've got a broken IPv6 tunnel :o/

Any ideas what's going on? Microsoft, anyone care to comment?
