Postcard from Havana
It would have to be a postcard. Internet is unobtainable in Cuba. Well, to tourists & plebs.
Not quite true, based on my 4 week trip there in 2018. You can buy internet credit at kiosks, and then input the 12 digit card number you are given to access an hour's WIFI at some local park. It is the worst thing (and maybe the best thing) about being in Cuba, the labor intensive frustrating way to get internet access.
Then as I found in Havana some of the local Airbnbs (casa particulars) have illegally somehow got modems into the country, and so can offer their tourist guests continous WIFI. Just don't tell the party officials
There is an innovative black market for everything on the island. Like from memory gambling is illegal, but there is an undergound lottery that uses the last 8 numbers of the actual Florida daily lottery or something crazy. Fascinating joint. And yeah the 1959 revoluation there was a very good thing initially, the place being a corrupt murderous Mafia fiefdom prior. But the Commies have stayed in power there now way past their use by date. I digress.
