The internet is now a big liability when there is an emergency, as we see today. Not only does it spread false information without controls, inciting panic in some cases, apparently it has the ability to sway the out come of elections. If we depend on the internet as a medium for communicating vital information in an emergency, it becomes difficult to do so when traffic itself is incredibly high, as it most certainly will be. The increased volume of information leads to an overload that "swamps out" any urgent messages that need to be sent.
Simple example- Charity groups and many other organizations that depend on donations are seeing complete downturn in financial support. Yet the problems they deal with continue, the virus does not give our society a break when it comes to these problems.
There is no way in the current media frenzy for them to get a message out. The same would apply to other types of urgent situations.
