The current report presents telephone, postal, telegraph and computer data from 2008-12. Here are the computer and networking statistics:
Bear in mind that these statistics, like those of other nations, are self-reported to the International Telecommunication Union.
I assume that the numbers of networked computers and number of Internet users refer to the Cuban intranet and the Internet combined. (While most of the other indicators are defined in the report, these are not).
The number of .cu domain registrations grew by only 2.6%, which is a bit surprising given the recent emphasis on private business.
Mobile coverage is the "star" statistic, but, as far as I know, it is all 2G at this time and the growth in infrastructure (coverage) was considerably slower than subscriber growth. The same domestic infrastructure problems that have plagued the Internet and access to the undersea cable restricts back-haul from cell towers.
