I'm the author of this post. The article has been updated to clarify that I accidentally published it one day before the embargo lifted. GitHub will formally announce the news tomorrow.
I'd be interested to see if you do a post-mortem on this - what the consequences were, and what steps you end up taking to ensure that it doesn't happen again.
One way to help ensure that it doesn't happen is to take steps to prevent it and post a post-mortem explaining both what caused it to happen and why it won't in the future.
