I just opened Bitblender website, and there is no any information about closing business. This can be very problematic and they need to turn down his website. Here are many people who are using his service, but he did not come in the forum every day and stay on top information.
You don't see any message about Bitblender shutting down on their page because they don't mix coins on the regular site.If you follow the instructions and used the tor link you'll see the exact message which bitblender also posted on their ann thread linked by astville above.
Bitcoin Blender is shutting down. Please withdraw.
