Some very nice IPv6 growth as measured by Google

That is not what I wrote or intended.

Something unrelated to their deployment broke. But doing the deployment
does mean that you are now providing connectivity that breaks to two
major providers: Google and Akamai.

Tunnels do not suck, people who have broken clusters that randomly drop
packets suck. Note that even with a full 1500 MTU you will have broken
connectivity to Google at the moment, lots of fun thus for those native
deployments like Unitymedia who forcefully stuff folks in DSlite land.

Currently that is both Akamai and Google. Both of which have been
working for a long long time.

At least Akamai is claiming to be looking into it, but with their recent
multiple Location: header fiasco I think they have more on their plate.

Note that this broken connectivity just gives a "Disable IPv6" cry from
a lot of people, which is a really bad thing.
