The “kind of service restricted” during internet shutdowns refers to the specific internet provider technologies that are disabled or blocked during a government-ordered interruption. These typically fall into three main categories: mobile internet (data services on cellular networks), broadband (fixed-line internet connections to homes and businesses), or both simultaneously. A mobile shutdown targets only cellular data while leaving wired connections operational, broadband shutdowns affect only fixed-line connections, and combined shutdowns disconnect both types of internet access, resulting in a more comprehensive disruption of online communications.
