Coming from you, I am not surprised :-)
We need to well document this deployment case for other universities
to follow around the world.

> Yesterday evening starting at around 7pm one of the South African
> universities turned up IPv6, in a fairly consistent manner. Now,
> I'm not talking about turning up IPv6 on a few servers, I'm talking
> about integrating it into every part of their network. By 2:30am
> this morning it was running on all their proxy servers, all their
> residence networks, the wireless networks, all the lab PC's and a
> good portion of the staff network. The topology used was identical
> to that of the IPv4, and as the rest of the network is migrated to
> the new IPv4 topology V6 will be implemented on everything in dual
> stack along side that as well.
> Now, here is where things get interesting, another network dual
> stacked is no real news, so lets talk about traffic levels.
> The University in question is now running anywhere between 30 to 50
> percent of its internet traffic on IPv6, and its working flawlessly
> so far. So flawlessly infact that even with Apple's default
> implementation of Happy Eyeballs that tests RTT and defaults to v4
> if the v6 latency is higher, the apples we tested on running lion
> and mountain lion were still choosing ipv6 most of the time.
> I am not going to say this little rollout has been easy though, we
> had to rearchitecture the entire network (that had to happen anyway
> for various reasons), and we added the v6 as part of that project.
> It would not have been possible to do that without first getting our
> hands on another /15 worth of IPv4 space though to allow that
> rearchitecturing to happen properly.
> As I said though, in coming days we'll write up what we did with a
> lot more detail and send through some graphs and other information,
> I just had to share the fact that we're seeing at points half the
> traffic on a standard university coming in from the internet over
