Why did MSNBC delete this story?

In searching for news stories about President Bush supposedly being "insensitive" towards the tsumani disaster in Asia, I discovered that MSNBC has removed this story (cached copy) from their website. It still can be found using their archive search (search for "insensitive tsunami"), but it comes up as "File not found." Other older articles (some dating back to early 2004) are still available, so why not this one?
