Frequently Asked Questions
Was it a bug?
No, it was a perfectly executed bad design. The system did exactly what was asked, but the requirements lacked any boundaries.
Why do systems work 'as designed' but fail in reality?
Because the design only considered the happy path. When real-world load hits the system, the lack of constraints turns features into weapons.
How do you prevent 'working as designed' incidents?
Always implement hard limits, pagination, and circuit breakers, even if the product manager says 'we will never have that much data'.
Why did this happen?
Root ownership issue hidden behind processes.
