What happened to the ADO.NET 3.0 May CTP?



It was announced here
http://bloggingabout.net/blogs/erwyn/archive/2006/05/11/12167.aspx and then
within a few days, it was so completely removed from MSDN ...it was like it
never existed.
Why was all of the documentation for ADO.NET 3.0 May CTP removed from MSDN?

p.s. The only thing that continues to exist is the HTML forum:
