> Unlike NASDAQ that can rollback/shutdown the market, MtGox has to maintain 24/7/365. I dare say their market's uptime is more critical than the regular stock market. You are trivializing the real markets. What makes you think this is something that NASDAQ can just "do"? They had a system problem causing delays on Facebook's IPO, and they're still dealing with the shit-storm from that now. Everyone who had poor executions (or missed executions) as a result of the delay is trying to get compensation from the exchange for their technical problem. I haven't checked the exact number recently, but I want to say $21MM is the pool that the exchange has to puke to the "plaintiffs". Because bitcoin exchanges are not regulated in the same fashion as stock exchanges, I doubt that MtGox will be on the hook for anyone's poor executions. > I wonder how their stack is setup. As someone else pointed out, their stack is setup wrong if account management has _any_ impact on their matching engine. Hopefully, it was just the web servers which host both accounts-management and trading UIs. Regardless, there was clearly some resource-sharing which should not have happened.
