Google have their own data centres (and cloud) so it may be something more in the connectivity area.
Maybe, I would expect redundancy. But ultimately I have no clue. I just remember the last time AWS went down. It seemed that a majority of the sites that I used daily were down all in one go.
Sometimes redundancy doesn't help when it comes to network traffic routing. That system is based heavily on trust and an incorrect route being published can cause recursive loops and such that get propagated very quickly to everyone.
There was a case like this a few years back where a bad route got published by a small ISP, claiming they could handle traffic to a certain set of destinations, but then immediately trying to send that traffic back out again (because they couldn't actually route to that destination), which bounced right back to them because of the bad route. It was propagated based on implicit trust and took down huge chunks of the Internet for a while
So could this be done maliciously? I'm just wondering about the Super Tuesday timing.
Yes, BGP Route Hijacking can be done maliciously although things like BGPSec can make it harder to pull off.
You're talking about Border Gateway Protocol, BGP, route hijacking and it's occasionally been a real headache over the years. Advertising routes used to be a more manual process so typos and incorrect entries, like what you're talking about, we're reasonably common. It was, and still can be, done maliciously too.

Yup! BGP is an absolute mess and it is kind of a disgrace that it's still the lynchpin of the internet
Yeah, they definitely host an unhealthy amount of the internet.
