The work of trying to connect the internet for the country's eleven million inhabitants was still ongoing late into the night, local time, without a prognosis for when the disruption can be rectified.
Energy Minister Vicente de la O Levy wrote on X that the work of restarting the network is ongoing, but it must be done safely, step by step, to avoid new disruptions.
Millions of Cubans were affected already on Thursday evening, local time, when a large part of the network stopped functioning. Large and recurring disruptions are common, but not total ones.
The latest disruptions have led the government to declare a state of emergency, close schools and public institutions to reduce consumption. When the large power plant Antonio Guiteras failed on Friday, half of the electricity disappeared and led to the network collapsing.
