Bookmarks gone issue

Idk if this related but with all the recent sites getting shutdowns and now many people lost their bookmarks in this site, I have a feeling that it's mangago way to prevent this beloved site getting shut. Because earlier this day around 3PM I couldn't even open the site(Probably maintenance). At first I thought they got our site too, but then I'm able to reopen the site again at 19PM, with all the bookmarks gone ofc :))) I might be wrong though.
