The duration of internet shutdowns refers to the length of time for which internet services are intentionally disrupted or disabled in a particular area. These durations are typically categorized as short-term (less than 24 hours), medium-term (between 24 and 72 hours), or long-term (above 72 hours or three days). The duration is measured from the moment internet services are restricted until they are fully restored, with longer shutdowns generally having more significant social, economic, and humanitarian impacts on affected populations.
