I have to say I have some sympathy for the Robinhood engineering team. Whenever I see something like this I’m reminder of the infamous S3 outage that Amazon had. How a typo took down S3, the backbone of the internet - The Verge
From the outside Robinhood look like a strong engineering team. Importantly they’re trying to move the industry forward and greater change => greater risk of failure. We’ve tried to mitigate some of this risk by pushing our infrastructure to Google but as in the Amazon outage above there are still risks. All that said I hope that if we do run into issues we communicate more clearly than Robinhood did in this instance. It looks like updates came late and didn’t give customers much opportunity to react.
