Picasa retired??

I just tried to link one of my photos...long story short, Picasa has been retired!!
Somehow, they have maintained the links to previously posted stuff, but all of my bookmarked Picasa sites (including my own) are now invalid.

I'm not sure how or where to find the address for my photo albums that now reside at Google Photos.
Anyone else notice their Picasa sites vaporize? Or am I some sort of stone age hold out??
