At the time of the last hacking incident, this was pretty much the only mirror of PE. Since then the textfile has been updated and includes some (hashed) answers.
Project Euler people, there's no shame in unbundling your problem set and your web app. Actually, those are two different projects, so unbundling them would be technically sweet. Release your problems on GitHub or wherever. Do the webapp as a related project.
keenerd, any chance you saved the HTML for the problems as well? If so could you release it? As nice as it is to have text versions of the problems, I'm suspicious some things were lost in the transition, e.g. if they used italics anywhere.
