He's likely talking about trading circuit breakers which trigger when the market is down a substantial percentage in a short time. Trading is suspended for a period

With COVID it happened twice iirc - the stock market has been automatically stopped to prevent panic runs.

Online trading platforms also go down...just like crypto exchanges. The tech stack has to be incredibly resilient and fast, several steps above most software in terms of performance and reliability.
