The only company in the world who can claim to have made a perfectly horizontal system at all levels of macro and micro is amazon, and even they would be lying to do so. A system like robinhood can have hundreds of moving parts, if 99 of them are horizontally scalable but 1 is not, eventually that 1 piece will become the bottle neck, and the fact it hadn't been made horizontally scalable yet is more likely to be a testament to how much work would have to go into doing so. > Heads. Should. Roll. Tell us the post-mortems, and then tell us who got the boot. Completely unacceptable. This is an unfortunate viewpoint. How quickly did we forget that robinhood is literally providing a service that no other company was able to do before. You want 100% uptime, you won't find it in an online service, let alone an online fee free service, you'll find it on the floor of the exchange.
