In fact, there have been some HN posts lately talking about having a backup CA, since LE is not the only free CA that allows automation of cert creation. Hopefully everyone has documented all the systems that auto-generate certs, what certs they request and put that in a manifest so that they can have a contingency plan, in the even that LE is knocked offline or shut down for whatever reason. It can certainly happen.
