Connections in globalisation are rarely continuous or uniform. Interruptions occur when established flows of goods, people, information, or capital are slowed, blocked, or temporarily terminated. Their significance lies in contrast to existing connections – they expose vulnerabilities, prompt adaptive strategies, and can reshape social, political, and economic processes. Historical examples, such as the global telegraph network in the 19th century, show that interruptions – whether caused by technical failures, theft, or conflict – were central to the development of global communication. By analysing interruptions, we capture the fragility, contingency, and unpredictability inherent in global integration.
