Thankfully this one has some archives. But indeed, not everything does. Even with some backup, the Internet has not always proven itself to be a reliable means of archiving things. Companies (and their websites) vanish, and not always with a working archive somewhere. YouTube channels routinely vanish, along with their content, and in many cases it's on you to back something up (using third-party libraries).
