Anyone who has used the internet can tell you that individual websites, webpages, articles, videos, etc. pop up and disappear every single day.  All is not lost, however, as librarians, governments, and other actors attempt to preserve the internet for posterity, with increasing effectiveness and sophistication.  Here are some web archiving efforts and organizations that may be useful for your research, especially if it depends on materials that are at high risk of disappearing from the internet, or have already done so:
