Is this your first day of trading or something?

People lose money in trading all the time, for hundreds of reasons and some of those reasons are infrastructure downtime.

If your risk profile doesn't reflect that, maybe you should take your money out of trading altogether.

Nearly every online brokerage has had an outage or outages in the past.

Nothing was stopping the Robinhood customers from opening an eTrade or TD Ameritrade account or something and doing their trading out of that platform for the duration of the outage. Robinhood isn't really an institutional platform in my understanding anyway.
