Submarine Cable

We had encountered severe internet congestion last two weeks due to earthquake in Taiwan. But my company also faced the problem on unnecessary packet transmission from the Internet Messaging Service (IMS). Statement below from Jame Seng clarifies my understanding on submarine cable. I first thought that the cable is laid under the seabed.

“Submarine cables are not under the seabed. It is just laid across the sea. It is only when it crosses major shipping lines and fishing zones (mostly near the coast) that it is lay (5 to 10m below) under the seabed. Therefore, it is not unusual for submarine cable to be cut, mostly due to deep-sea fishing”
