SimCity (2013) always-online server launch failure
EA's rebooted SimCity, which required a constant internet connection even for single-player use, was nearly unplayable for days after launch due to server overload, prompting an eventual apology and free-game giveaway from EA.
The damage was public. The root cause was preventable.

What the software actually got wrong
The game's servers, which handled core simulation calculations for every player even in single-player mode, could not handle launch-day demand, and the always-online design meant players could not play offline as a fallback while the servers were overwhelmed.

Requs AI Edge Case flags this exact pattern at the requirements and architecture stage — before a single line of code implementing it exists — so the assumption behind it gets challenged while it is still cheap to fix.

Requs AI Software FMEA traces this failure mode back to the system-level hazard it feeds, tagging it against the Common Defect Enumeration so it surfaces in review instead of in the field.
Beyond code coverage and "shall" testing
Root causes like this one rarely show up in code coverage or requirements-compliance testing, because nobody wrote a requirement anticipating the specific edge case that broke. Requs AI Edge Case and Requs AI Software FMEA are built to surface exactly this class of overlooked failure mode — before the software is written.
Surfaces this before code exists
Identifies edge cases like this one at requirements and architecture time, using the Common Defect Enumeration to catalog failure patterns seen across hundreds of real-world software failures — including this one.
Connects the failure mode to the hazard
Traces this class of root cause directly to the system-level hazard it can produce, so a defect pattern like this one gets flagged during design review instead of after it ships.
Find the overlooked root causes before they ship.
