Generally I enjoy archive.today very much, but it seems to be a labour of love which can go away any moment (despite its apparent resiliency), rather than something for the ages...
This is why I consider these types of archives important: not so much to bypass paywalls, but to ensure content is still available in a decade, or two decades.
