Firstly, welcome to Yorkietalk!
Website, phone and youtube down? The website redirected to a domain provider site so maybe it is a case of her not paying whatever the price is to keep her domain? Or it expired? Idk if that can happen or not, just a guess. Maybe the website is just down for maintenance or moving to a new server? Looks like her youtube videos are still there though, just from a quick google search. Idk how to explain the phone number. Kinda strange.
I would keep trying...it is a good idea to keep in contact with your breeder for your pup's entire lifetime, if possible. Can you email her? I'd start there and let her know her site is down.
Here is a thread that came up in a quick yorkietalk search of littlebieweryorkies.com:
