Cuba USA
Doug Madory of Renesys, an Internet monitoring company, has reported that Cable and Wireless is no longer carrying traffic between Jamaica and Cuba, Telefonica is carrying less traffic than previously, and Tata is carrying more. Furthermore, the Tata traffic has shifted from satellite to the high-speed undersea cable, as shown in these improved traceroute times from Miami:
As we see, around June 25, Tata traceroute times from Miami dropped from about 580 milliseconds to about 130 milliseconds, indicating a shift from satellite to the undersea cable. At the same time, Telefonica traffic from Miami stopped. (The central band at around 330 milliseconds indicates asymmetric traffic which is over cable one way and satellite the other).
You should check Doug's post -- it contains several other plots and links, including one to an article on Fidel's birthday that says he likes to surf the Net. This reminded me of his early recognition of the importance of information technology, expressed at the time of the opening of the Youth Computer Club headquarters in Havana in 1991.
The undersea cable has brought faster connectivity to Fidel and a few others, but without improved domestic infrastructure, service will remain poor or nonexistent for the majority of the population.

- Cuban International Traffic Shifts From Satellite To The Alba-1 Undersea Cable
Doug Madory, Director of Internet Analysis at Dyn Research, sent me a note on Cuba's international traffic. As you see here, on July 1, nearly all satellite traffic (blue and green) was re-routed to the ALBA-1 undersea cable: As a result, median...
- Cuba-jamaica Link Of The Undersea Cable Is Operational
Doug Madory of Renesys reports that the Cuba-Jamaica link of the ALBA-1 cable is carrying Cable and Wireless (C&W) traffic. The first plot shows Transit, a Renesys-defined metric which is a function of several variables and may be interpreted as...
- First Traffic On The Alba-1 Cable
Doug Madory, who has been keeping us up to date on traffic (or the or lack of it) on the ALBA-1 submarine cable between Venezuela and Cuba pointed me to a new blog post this morning, in which he reports limited cable traffic. For the past six years, three...
