It might not be gone for good. The site has been broken and more-or-less unmaintained for several years and has been down before, I think. Things like the advance search haven't worked in ages and many authors no longer show up in the author list (so you have to know the exact URL to get to it).

There are still active authors on the site who are probably pretty upset right now. It's not a matter of donations because they get enough money. It's just that no one is at the helm. I really hope this is temporary. I was just on the site two days ago (first time in months I visited it) and it worked fine. Then yesterday it just stopped working. I even had a few tabs open still!

Archive.org has a few 40 gig archives from 2015 to 2017.
