I book mark free model sites I like, and go back to them from time to time to see if there is anything new. Today I was bored, and was going through my book marked pages and Paper Robots 1999 was gone. I tried the wayback machine and it gives me the home page, but I have not tried to download any models because I already have the ones I like. Here is the wayback address for those who want to get the models = http://web.archive.org/web/20150219052809/http://paperrobots1999.com/models.html . I have also post some screen grabs from the home page of some of the models.
