Hi Guys,

So, while i'll be sending out a lot more data soon, with a lot more =
information on exactly what we did and how we did it etc, I thought  I =
would share some news that I for one found rather exciting.

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 ipv6!

Thanks
