Yeah, it seems that it's been abandoned alright.
The Google cache pages are still up for now, though, so you still may have a chance to grab whatever it is you're looking for on her site.
What I'd suggest you do if you really need something off of the website is to use Google to navigate through the cache pages while you still can. If you have the ability to right-click on a link and copy it's url location, enter it into Google's search field and it should bring up the page info. Once you click on "Cache", you've got yourself a ticket into the site. The download links are still good, since I'm also in the process of navigating the cache of the site myself and backing up a list of links to her content while I'm at it, but there's no guarantee how long these cache pages will remain up since there's not to much info on when exactly GP's site went down.
Hope that helps you.
ETA: The site seems to be back up now. I was mistaken earlier, since the last post that was made on her site happened to be last week in fact, so I'm glad to see she's still around and ok.
