Hard to judge _worse_ in this context but while I was trading all of CME globex was down for 4 hours canceling active orders. https://www.profit-loss.com/cme-hit-by-globex-outage/ https://www.profit-loss.com/cme-hit-by-globex-outage/ I don’t remember them offering any apology or explanation at all. That’s an exchange mind you where things like the global price of oil and s&p futures trade. Not a small boutique brokerage. Further they have planned downtime every week & at that point still had planned daily downtime I think. I think Robinhood screwed up. I think they should learn a hard lesson. But people thinking that trading is some high reliability industry haven’t spent any time in it. The scary thing to me is are healthcare, aviation & food the same?

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.
