[edit] Damage
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.

[edit] 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.
[edit] 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.
