I fixed a broken link in one of my more wretchedly trollsome old posts with the help of the magical Internet Archive. I noticed two things while creating a local mirror:

1. You can’t use wget on the Archive, as the links are left pointing to the old, presumably AWOL, site and then resolved with JavaScript. Will there ever be a JavaScript-aware wget? Unlikely.
2. Sites can disappear from the Archive, even without the original author requesting their removal. If you lose control of your domain, a new owner can buy it and install an Archive-unfriendly robots.txt file, which will wipe all that domain’s history from the Archive. Keep control of your domains, people.
