Part of AWS's sell with elasticity is only spending what you need, but those industries have redundancies or unused capacity.
Someone in one of these threads said there's a hidden DNS within VPCs that can fail and isn't scaled, so if that's true, they might just have to architect around that unless they can get AWS to change it. It's on RH for not knowing that but it's also kind of on AWS too.
But as far as what you can do, you can really only split your cash across brokerages if you want to engineer the same redundancy yourself. Otherwise, RH would need to route everything to another exchange to keep satisfying orders, and even that is just another system that could fail. Keeping all of your money in one brokerage doesn't seem ideal if you want to completely avoid downtime. Doing the same redundancy yourself with those industries isn't really practical.
