IPv6 traffic percentages?

[nanog-isp () mail com]

Hello all,

Would those with IPv6 deployments kindly share some statistics on their percentage of IPv6 traffic?

Bonus points for sharing top IPv6 sources. Anything else than the usual suspects, Google/YouTube, Netflix and Facebook?

Some public information I've found so far:
- Comcast around 25% IPv6 traffic ( 
http://www.lightreading.com/ethernet-ip/ip-protocols-software/facebook-ipv6-is-a-real-world-big-deal/a/d-id/718395 )
- Comcast has over 1 Tb/s (of mostly YouTube traffic) over IPv6 (

- Swisscom 26% IPv6 traffic, 60% YouTube ( http://www.swinog.ch/meetings/swinog27/p/01_Martin_Gysi.pdf )

I'd be very much interested in hearing from smaller ISPs, especially those having a very limited number of IPv4 
addresses and/or running out. 


Thanks,

Jared
