When did all Cox markets first have access to IPv6?

All residential Cox customers in all markets now have access to IPv6, with the exception of the following.

• • Only Cable Modems and Voice modems are currently enabled to pass IPv6 traffic. 
  • WiFi Modems will be enabled for IPv6 during second quarter of 2016. 
  • G1GABLAST and Cox Business customers will have IPv6 enabled at a later date with a target of 2016.

When did this occur? I wish I would've been notified sooner about this. The first I heard about this was on this thread here.

thank you
