Internet Disruptions in Cuba Following Widespread Protests

July 16, 2021
The nation of Cuba experienced a complete internet shutdown beginning at 4:05pm local on 11 July 2021. The outage lasted about 30 minutes and was followed by several hours of partial outages.

Until very recently, large internet outages were very rare. Internet shutdowns are new to Cuba in 2021 but Sunday’s wasn’t the first. There was an outage in January that appeared to be government-directed following additional protests motivated by the 27N movement.

In addition, the Open Observatory has documented censorship targeting Signal, Telegram and Whatsapp.
