As to the question of whether Cuba may be censoring content, Madory wrote that is likely not the case. Countries using technical means to control content often show noticeable daily traffic patterns.

The latency patterns noticed in Cuba appear "very similar to cases of asymmetric satellite" patterns that Renesys has observed in the past, Madory wrote.
