Northern Star is probably going out of business

lt looks like Northern Star - the manufacturer of the Data Tresor and M-Disc DVD media (and formerly also the infamous Multidisc DVDRs) and possibly the very last recordable media producer in Europe may be going out of business.

They are trying to sell their manufacturing equipment via used machinery dealer Add-Y-Pac here:

Seems so, the domain is down, however the DTD website got update in August 2017, so some operations were still in place at that time.
I wonder if their E-shop still works.
