Humans Prove Weak Link in Japanese Warning Network
Martyn Williams writes on NetworkWorld:
If there's one thing the Japanese government learned on Saturday -- the first of a five-day launch period for a North Korean rocket -- it's that the government's emergency information network works.More here.
At 12:16 p.m. local time, terminals at government agencies, municipalities and media organizations across Japan flashed news from the government: "North Korea appears to have launched a projectile." Almost immediately TV stations broke into programming to deliver the news and soon after it flashed around the world.
Too bad North Korea hadn't actually launched anything. Five minutes later the same network was used to retract the warning.
The error was blamed on a misunderstanding between military staff. A radar station near Tokyo had detected something over the Sea of Japan, which separates the two countries and over which the rocket was expected to fly, and this was relayed to Japan's Air Defense Command. But there, according to local media reports, it was mistaken for data from a U.S. early warning satellite and passed on to the Defense Agency and central government and the alert was issued.
