Hengchun earthquake cuts Asian cables (2006)
A magnitude 6.7 earthquake off southern Taiwan on December 26, 2006 severed eight submarine cables in the Luzon Strait, including segments used by Asia's biggest carriers.
Internet access across China, Taiwan, Hong Kong, Japan, South Korea, and Southeast Asia degraded for weeks while ships repaired the cables at sea.
The outage pushed carriers to diversify routes, but landing-point concentration persisted, exactly the pattern Sta'O'Nuk challenges.
Shows what happens when cables share geography: one event knocks out multiple systems at once.
