Everyone assumes their emergency alert system will work because it worked yesterday. But urgent communications events don't break technology — they break assumptions.
Real humans don't follow your QA scripts. They mash buttons, hang up in panic, call back repeatedly, hit voicemail. Generic load testing can't model this. And you won't know your system fails until 40,000 people need it at once.
