Yesterday, there was news break by Google that Google entirely delisted Digg from Google’s search index. Some people were saying that it was a problem with their site robot.txt, some thought it was a Google issue and weren't sure what it was all about.
Google also shared their official statement as well:
We're sorry about the inconvenience this morning to people trying to search for Digg.
