How do we cope when the tech we rely on stops working? This week we look at different types of blackouts . We explore the Bangladesh internet shutdown, which affected up to 170 million people for 10 days. We turn to South Africa, which experienced 15 years of daily power outages until very recently. Then to a country which still experiences blackouts now - Cuba. We meet the game developers who work even when the electricity cuts off.
