step 1 of this post is done. tbone users are done with their readonly window.

step 2 will happen in 30-40 minutes. we're doing a backup of the old tbone data pre-deparenting just to be paranoid. until this finishes, the site will remain slow for free users. once the backup's done we'll be able to reuse the old tbone master as another slave to help out chef users, and the whole site will get faster.

If you look at the bright side, only 9.2% of our active users are still on MyISAM (which can't really cope with concurrency at all, at least not without dirty hacks).... Once we're done converting chef hopefully we can ignore databases for a bit. So far the InnoDB machines we've already converted have been great.

Updates as they come...
