Chaos engineering

What would happen if, one of the production web servers, suddenly goes down?

«Between 10am and 11am, an average of 100 orders per minute is handled»

«Between 8pm and 9pm the homepage is requested 1000 times»

«What if communication with the database suddenly had an extra 100ms latency?»
