The first thing I remembered was the deletion nomination spree that took down a bunch of programming language articles a couple years back (https://news.ycombinator.com/item?id=2215168 https://news.ycombinator.com/item?id=2215168). It took quite a bit of internet backlash for this to get noticed and reversed - something that probably wouldn't happen for lesser known articles. I can't cite any other examples off the top of my head, but I know I've run into dead bookmarks once in a while for obscure Linux/OSS related articles on Wikipedia. Though I guess it's debatable if those lost articles really had any worth.
