Her website hadn't been updated for some time; I'm assuming that she just lost interest in the brand .. we've seen it happen to many (alas) former enthusiasts. The best (EVER) website for Balenciaga was some years ago .. I remember the title had the British term 'NAFF' .. because she had a behind-the-scenes history of how the Motorcycle style even came about. She had comparison pictures (fakes vs 'real'), etc. -- it was fantastic but sadly, some trolls hit her site and she decided to shut it down.
Corey on the Real Deal Collection (realdealcollection.com) has some good "oldies" information; not sure about more current stuff ..
That's so odd, because I pinned some pages from her site on Pinterest in February, and the links all worked back then. You can still view the cached pages using the Wayback Machine, though, so there is that.
