Well, site owners do have the option to remove links when it suits them and that happens a lot. They have their own reasons for removing external links. In other cases, the site may have been taken down, for one reason or another.
I myself have just taken down a blog which isn't doing well and on which the domain registration is about to expire; I have decided to let it go because it just is not worth the investment in time and money anymore. Because I took it down, the backlinks from it are also gone. I plan to take down a few more, or rather just let them die naturally (when the domain registration expires), and of course backlinks will die with them. It's sad for those sites to which they link back to, but they really have to go.
Hence the need for continual backlink building. You cannot always be sure that your backlinks will be there forever.
