100-word summary
Two outages in three days this March cost Amazon 6.4 million orders. The culprit? Its own AI coding assistant, Q, helped generate changes that slipped past safety reviews. One undocumented tweak tanked North American orders by 99%. Another scrambled delivery times, triggering 1.6 million website errors. Amazon's response is a 90-day lockdown on 335 critical systems. Every code change now needs a second human reviewer and formal approval before going live. The company is betting that pairing AI speed with old-school human oversight will catch what automated checks miss. The irony: tools meant to help engineers move faster just forced the retail giant to slow everyone down.
