This is why it's important to download copies of articles (or even entire websites) that you like. I used to do this more often, but I've gotten lazier and the Internet Archive has gotten better at what it does. I have had moments where I've gone to look for something I saw years ago and been unable to find it, even in the Wayback Machine.
The impact of this can be seen in practically any Wikipedia article. Sources are cited, but when you go to look up the source, the link is broken. Sometimes, you can find another address for the source and re-link it, but many times it's just vaporized.
