Credit goes to Mark Bergsma, Faidon Liambotis, Ryan Lane, Asher Feldman, Aaron Schulz, Chris Steipp, and many others for helping make this happen. Many members of the team worked practically nonstop to ensure that we can launch on IPv6 Day. Here's a full update from Mark:
[begin quote] Today, between 10:00 and 11:00 UTC, we've gradually enabled IPv6 for all wikis. We started with upload, followed by bits, then the main wikis, and concluded with the mobile cluster.
So far it seems to be working fine. We're seeing some edits being made over IPv6, and IPv6 traffic is in the low tens of Mbps range. Browsing the sites over IPv6 seems to just work like it does with v4. I haven't heard of a single complaint yet. It was very uneventful. :-)
Nonetheless, there will be a very small (fractional) percentage of clients who no longer can access our sites. Part of the idea of today - IPv6 Launch Day - is to collectively force these clients and relevant network issues to get fixed. Faidon has also improved my old "selective-answer.py" DNS backend, previously used for IPv6 DNS whitelisting, to allow it to be used as a blacklist. If we find networks that are unable or unwilling to resolve any IPv6 issues, then we can selectively disable IPv6 for their IP address prefixes. This is not in use yet, but can be deployed quickly.

There will surely be new MediaWiki or tool/bot level issues as well, but hopefully they'll be manageable without a rollback. The best way to report most issues is through https://bugzilla.wikimedia.org/ and by adding the "ipv6" keyword.
