Taiwan quake causes net blackout

December 28, 2006 - 9:33AM


Telecommunications across Asia were slowly being restored on Thursday after 
earthquakes off Taiwan damaged cables and knocked thousands offline, but access 
in parts of South Korea and Taiwan was still patchy.

Most of Asia's telephone traffic was restored while internet access in many 
countries had also improved, a day after businesses and home users from Seoul 
to Sydney were hit by one of the most widespread tech disruptions in Asia.

South Korea's top fixed-line and broadband operator KT Corp. said six submarine 
cables owned by a consortium of telecoms firms had been disconnected on 
Wednesday, knocking out thousands of telephone and broadband connections.

KT Corp. restored most of the telephone services but broadband services for 
some clients, including banks and the country's foreign ministry, remained 
unavailable.

"As of late Wednesday, we were told that broadband services to 32 clients were 
affected,'' a KT spokesman said on Thursday. Local media reported that 36 
foreign bank branches in South Korea had been affected.

KT and other regional operators have warned that fixing all of the affected 
cables could take at least a few weeks and are working to find ways to run the 
traffic through other live lines.

But business in the tech-savvy region appeared little disrupted, with stock 
markets slightly higher or unchanged on Wednesday amid lacklustre trade ahead 
of the New Year holidays.

In Taiwan, some telephone services had been restored, although international 
access was shaky, and early morning Internet access also appeared to be working 
normally. Foreign exchange dealers said trading services were also back to 
normal.

Singapore's central bank, the Monetary Authority of Singapore, said trading on 
Wednesday had been conducted over telephone instead of the e-bond platform.

"Trading volume is typically low this time of the year, but dealers noted that 
market liquidity is readily available if they need to transact,'' a spokeswoman 
said in an e-mailed statement.

Analysts said the disruption highlighted the fact that the most of the region's 
cable networks are running in the same direction, along earthquake-prone 
geographic lines.

"People will start to say we can't let this happen again,'' said Frank Dzubeck, 
president of Washington DC-based telecoms consultancy Communications Networks.
 
"The issue here is parallelism, you've really got to have multiple paths. You 
can't lay all the cables in the same place.''

Dzubeck added that the Internet bust in 2001 had hit expensive plans by various 
companies to lay undersea cables along new paths that were less likely to be 
affected by earthquakes.
