She used to provide, and her husband/boyfriend was a male performer who was about 20 years her senior. She used to live in Las Vegas and tour regularly. I saw her 3x within the span of a year in the same city.
It appears they are no longer together. She appears to be living somewhere near Tampa or Orlando now. I recently contacted the agent I used to book her previously, and the agent said she no longer works with her AND that Ariana no longer provides. It wasn't so much of an agency as it was a personal assistant, since he/she only used to book Ariana.
It is confusing because as others have pointed out, she does occasionally check her preferred411 page. She also has a banner active on EROS if you look under Tampa. To add even more confusion, there are relatively recent reviews on another web site. For all the reasons mentioned in this paragraph, I also wondered if she was available. I am certain that she isn't.
She shoots very little content for production companies now, and by her own words does so just to maintain status and recognition in the industry. I'm sure she does pretty well making her own content -- she was doing it before it was even popular.
I think it is possible, but unlikely, she returns to the hobby one day. Based on my conversations with her, she seemed goal oriented, and her involvement in the industry was a means to an end. I see her doing OF until it is no longer lucrative, then retiring.
