It might have something to do with recycling the space on a server, or perhaps because they feel the information is dated . . . but this has been occurring for years (not because of any changes that happened recently).

I recall when Tysabri started to come back to market, the old articles disappeared into their "search" filing cabinet (they were still there, just not at the link that they were once at), and the link took me to the "this page is no longer available" notice.

The problem is that I keep the link so that I can attach it to postings, and so I don't have to copy the entire article. I don't keep the name of the article though, and even if I did, it's not always easy to locate again with their "search" function. Basically I have to try to recall some of the key words, then go "searching" (like googling) through their library of information by reviewing each article. I have found some that way, so I know at least some are kept anyway . . . the hard part is recalling the key words, then finding the specific article again.
