I managed to order from them on Sunday, and got a reply from Claudio when I had a question about my order.
I did, however, get to their shop via a direct link to a product page that I had saved rather than via the main menu (the main menu, when I wanted to navigate to another page, was telling me that their shop was "closed for maintenance") and note that if I try the same thing now I get the "shop closed for maintenance" message wherever I click.
Not sure if that's helpful, but I'd suggest that it means that Baueda is okay but that the website is genuinely "closed for maintenance"!
