I admit I am not an IT guy but I thought the whole point of the Internet was that is a NET. It was in invented to keep disruptions from preventing launch orders from being transmitted. I don’t recall ever hearing about an Internet outage in the past.
Well, sure... The Internet is a web, in theory. Originally the idea was for a national communications web where huge holes could be blown due to nuclear strikes, and the packet-based traffic would still hunt for any viable path around the holes. Of course... That’s back when email was most of the load and it was simple and text based and only a few kilobytes per message. There were open relays... So a message would bounce around front server to server playing a sort of “warmer... colder...” game until it found its destination. Open relays are unthinkable on modern mail servers. And... There was no WWW. There was telnet. There was pine. There was usenet. It worked and it was fairly resilient, if not so user friendly. But then the WWW happened.
Anymore the “web” is not a web. It’s more point-to-point with relatively few major backbones carrying the enormous volumes of traffic. Any outage of a key backbone route and just like a highway system traffic starts to back up. Like the airline system... If a major hub is taken out of action for a day... The flights back up in other airports and start to shut things down in a wider and wider area... And it can have nationwide and even global repercussions.
