James Governor at Redmonk has been told by Gartner that he cannot link to this page on its website.
The page in question is a reprint of the Magic Quadrant for Business Intelligence Platforms, 1Q06. You can still access the report (free of charge) directly from the website of the people who bought the reprint, SAS.
The link is also available from our friends at ARmadgeddon.
And Rob Stevens has posted about it too.
It's on the Business Intelligence Knowledge Base where it was posted by someone from SAS and on the Intelliminds news page.
You can read the full story first hand on James' blog (make sure not to miss the comments).
Sometimes you've got to watch in wonder and amazement and just ask "why?"
For the sake of completeness, Gartner has since apologised. See the comments thread on this post from James.
