Hi,
We're finishing a large release this week - the new Control Panel - and there is one other item that we ran into specifically dealing with global images when we opened up San Francisco which we are resolving.
The new way that we will be handling inter region image transfers to give customers the ability to move their images where-ever they like, this is also something that we need internally to manage global images and make it easier to sync them between the current three regions, and going forward any other regions that we add.
There is a bit of heavy lifting on the backend in regards to this change, in addition we are modifying how images are processed for the new kernel update feature which requires us to recast all of the images into the new kernel management utility as well which is why there is a bit of a delay for adding new distros.
We hope to have made the majority of the necessary progress on these items by the end of next week so that we can get Ubuntu and Debian added and hopefully at the latest it will be early the following week.
