Some U.S. intelligence figures say they are concerned that the Chinese government could force Huawei and other Chinese companies to shut down the networks built with their equipment. But how likely is this highly disruptive scenario? It would certainly be self-destructive for the Chinese companies involved as their customers would replace their equipment as quickly as possible, fearing another shutdown. And it’s unlikely that 5G equipment vendors could bring down the entire internet because of extensive wired connections through backbone providers like UUNET, Level 3, Verizon, AT&T, Qwest, Sprint and IBM. The internet is designed to be robust and to continue working even if one part fails. Shutting down a 5G network in a country would be disruptive, but it wouldn’t bring down the internet.
