[citation][nom]c_for[/nom]"So far, the technology is not advanced enough to come up with an early warning system for natural disasters"If this system is designed to detect internet outages, how could it predict future natural disasters? It's cause and effect, and you can't read the effect before it's been caused.[/citation]
Early warning system means detecting the disaster as it happens rather than after or before it happens. The problem with this is that the disasters might not immediately disrupt internet traffic so it only detects the loss of internet traffic if the disaster or what have you after it has already done enough damage to disrupt internet traffic.
This is a useful way to look out for the changing internet policies set but governments such as more or less immediate notice of firewalls being set up, but it's usefulness as a disaster detection technology may be rather limited because most other detection technologies may have already noticed the disasters by the time the internet traffic is disrupted.
This may be able to detect some disasters before other detection systems so it's not useless as disaster detection. For example, an earthquake may go unnoticed for hours outside of where it hits, but the internet traffic could be down well before the seismic detectors notice the earthquake so it could tell us what happened hours before other detection tech knows about it.
This may help us get relief efforts set up a little faster. Theoretically, it could help get people saved from stuff like collapsed buildings faster and thus increase the chances of survival for the victims.
Also, knowing about another country shutting some traffic out and/or in could be an indicator of international aggression so the issues may be able to be resolved faster peacefully, or we may at least know that something worse is about to happen before there is an attack.
