On 27 Dec 2006, the 2006 Hengchun earthquake damaged the APCN 2 cable links between Shantou, China and Tanshui, Taiwan, and between Lantau in Hong Kong and Chongming, China. This disrupted Internet access to overseas websites from Asia.

About APCN 2

Total bandwidth capacity of Asia Pacific Cable Network 2 is 2.56 Tbit/s, made up of four pairs of optical fibres, each pair providing 640 Gbit/s by Dense Wavelength Division Multiplexing of 10 Gbit/s wavelengths. The 19,000 km-long APCN 2 cable system is built in a self-healing ring configuration, which allows fast rerouting of data transfers along APCN 2 in the event of disruptions. The cable system, as of January 2007, is progressively becoming operational. APCN 2 is designed to provide interconnection with other major trans-oceanic cable networks linking the USA, Europe, Australia, and other parts of Asia.

Restoration

Due to the cable damaging Taiwan earthquake, restoration has now been further extended to the 29 January 2007 which is the up to date timeframe. This would make it a month since the 26th of December quake sent Asia into the Internet Dark Ages. To date, more than 80 percent of bandwidth has been restored.
