Does anyone know what's happened to Primus Telecom?

This may have been discussed before, but as far as I can remember, this company's website used to be (run by a guy called Andy?). Now, this link just defaults to - a company buying and selling mobile phones! They also had but this takes you to a domain registration called saying it is now owned by Afone S.A.? Any help or clarification would be very welcome. ... and apologies if this has already been posted as a separate discussion.
