This was the original docgraph retraction notice.

We did not know it at the time, but the "Update Oct 5 2012" message that we took a screen-shot of would be the only acknowledgement that CMS ever made about the problem.

This is the second post on the DocGraph retraction. It documents the fact that CMS would not collaborate with us to ensure that the data they were releasing was correct, but the data was released and "looked right".
