Why this room

The mechanism itself, a physical anchor drag severing redundant fiber, is a simple, calculable engineered payoff, but the resolution path got captured by geopolitics (a failed-state permit fight), stretching the tail of the outage from a routine weeks-long repair into a five-month disruption without making the financial loss itself catastrophic, a textbook case of a risk starting in one quadrant and being resolved in another.
