I have also heard an unconfirmed report that the cable is operational and being used in some Venezuelan government offices to access databases they have stored in Cuba. That could be a pilot test for the ALBA-1 link.
That would be consistent with the Renesys data we just posted (http://laredcubana.blogspot.com/2012/05/hard-data-on-idle-alba-1-undersea-cable.html), but it would not be Internet connectivity.
Venezuela storing their data in Cuba reminds me of the International Center for Scientific and Technical Information in Moscow (http://www.icsti.su/portal/eng/index.php). During the pre-Internet days, they provided centralized database access for all of the communist nations. Today they are on the Internet, serving a different group of nations.
