Three days after the earthquake and tsunami that devastated the north-eastern Japan, communications are disrupted in and around the archipelago, but Internet access was more resilient. Fixed telephony. Power outages and damage caused by the earthquake disrupted the operation of phone lines, but it is the gridlock that has created the biggest problems.
The main Korean telephone company reported that shortly after the earthquake, the number of calls between its network and Japan, which has a large minority of Koreans has increased by 91 compared to normal traffic. Mobile phones. In Japan, where mobile penetration rate reached 94% and where the mobile phone is more than anywhere else, a fact of life, access to networks is difficult outside of Tokyo, particularly in rural areas.
The quake also destroyed an unknown number of base stations, cutting off access to areas affected by the earthquake. The three main operators have begun to deploy this weekend emergency mobile units, connecting to the network via satellite. Internet. Despite the disruption, the Internet remains largely accessible.
The figures of the main points of data exchange in Tokyo and Osaka, show that traffic is slightly below normal - and considering that a major disaster, network usage increases sharply for those have access. The company KDDI, which manages the undersea cables between the U.S. and the Islands, for his part confirmed Monday that one of its cables had been damaged by the earthquake.
An analysis of the damage is ongoing, and in the meantime the traffic is redirected to other access points. The damage also caused disruption of Internet access in the Philippines, Taiwan and Hong Kong. Given the extent of damage, network access remains appropriate. When the 2006 earthquake in Taiwan, which had damaged undersea cables, the damage had been more important.
Network density has also enabled Japanese archipelago maintain access to the Internet far more important than what had been Haiti after the earthquake of January 2010.
