I've been in Cuba dozens of times in the last fifteen years and I have never been unable to access a single web site. This is going back to when I used a dialup account from the apartment where I was living. Same was true when I used the U. of Havana computers, same is true using the government-sponsored wifi, same is true using hotel wifi. So let's just drop the whole "Cuban government internet censorship" meme, shall we? Since it's never existed.
