Southeast Asia's largest telephone company, and Hong Kong's PCCW Ltd. said Internet service in Asia slowed down after three earthquakes hit southern Taiwan yesterday. ``The Taiwan earthquake has affected several submarine cable systems in Asia, causing cable cuts near Taiwan late last night,'' Singapore Telecom spokesman Chia Boon Chong said by telephone today. ``Some customers might experience a slowdown in data or Internet access. Traffic diversion and restoration works are currently in progress.'' Taiwan was jolted by three earthquakes yesterday, killing two people and injuring 42 others, the island's National Fire Agency said. The tremors damaged undersea cables, causing a disruption to Internet traffic and some telephone calls in the region for customers including Singapore Telecom, PCCW, Chunghwa Telecom Co., Taiwan's biggest telephone operator, and KDDI Corp., Japan's second-largest telephone carrier. PCCW, Hong Kong's largest phone company, said data capacity on its networks was reduced to 50 percent due to the quake. ``Data service to Japan, Taiwan, South Korea and the U.S. were affected,'' said Hans Leung, a spokesman in Hong Kong. Two of Chunghwa Telecom's cables were damaged by the earthquake, resulting in ``near zero'' capacity for voice calls to Southeast Asia, apart from Vietnam, said Leng Tai-feng, the company's vice president of international business. ``The repairs could take two to three weeks,'' Leng said. ``We're doing our best to coordinate with other operators in the region to resolve the problem.'' Southern Taiwan The first earthquake, which was magnitude 6.7, occurred at 8:26 p.m. local time yesterday off Taiwan's south coast, the island's Central Weather Bureau said on its Web site. The second, magnitude 6.4, happened at 8:34 p.m. and the third, magnitude 5.2, occurred at 8:40 p.m. All three were centered in the same area, the bureau said. On Dec. 26, 2004, a magnitude 9.1 earthquake off Sumatra unleashed waves that destroyed coastal villages on the Indian Ocean from Indonesia to Sri Lanka, killing more than 220,000 people. Some of the areas have yet to recover. KDDI said its fiber-optic undersea cable in Taiwan was damaged, affecting fixed-line services to Southeast Asia. The company is re-routing phone calls to go through the U.S. and Europe and may take several weeks to two months to repair cables that are damaged, KDDI's Tokyo-based spokesman Haruhiko Maede said. KT Corp., South Korea's largest provider of fixed-line phone and Internet access service, said the outages affected overseas connections of the foreign ministry and Reuters, which use leased lines, said Kim Cheol Kee, a spokesman for Seongnam-based KT. KT is in discussions with foreign phone companies to redirect traffic elsewhere, Kim says.

I've wondered how many boats/subs exist for these repairs and if attempting to do them all in parallel is going to be a big problem. With 6 systems having outages, it will be interesting to see when various paths/systems come back online and if there is a gating factor in underseas repair gear being available in the region. - jared -- Jared Mauch | pgp key available via finger from jared@puck.nether.net clue++; | http://puck.nether.net/~jared/ My statements are only mine.

Just to give you an idea: (from http://www.cnn.com/2006/WORLD/asiapcf/12/27/taiwan.quake.ap/index.html) (c)2006 AP Tyco International Ltd. said it has a Taiwan-based cable-laying ship heading to the area for repairs. "Pretty much everything south of Taiwan has been reported at fault," said Frank Cuccio, vice president of marine services at Morristown, New Jersey-based Tyco Telecommunications. Cuccio expects the ship to be in position in a few days. It then takes three to five days to repair each cable, but mudslides set off by the earthquake can complicate matters by covering the cables, making them harder to retrieve from the bottom. Cuccio said the ruptures are more than 10,800 feet below sea level, too deep for the remote-controlled submersibles that otherwise would find the cables. Instead, the ship will drag grapnels along the bottom to find them. The cables on the deep ocean floor are just two-thirds of an inch, a testament both to the immense data capacity of optical fiber and the fragility of the links that form the global telecommunications network.

Much of the affected cables are managed under the SEAIOCMA (South East Asia Indian Ocean Cable Maintenance Agreement). I am not sure how many ships they have on stand-by in the region, but probably not enough to send out one ship to each of the faults, given that multiple faults have been reported on most cable systems. I presume, the more important cable systems - those with higher stakes for the SEAIOCMA signatories will get repaired first followed by others. thanks -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (Darwin) iD8DBQFFk3IZSo7fU26F3X0RApmJAKDZpWgD67Kuqq8lSs7wEQquCVbfbQCguf61 bnrQWB66C0pOjl+5O7TYmVU= =yVXA -----END PGP SIGNATURE-----
