Reuters AlertNet says (props, Vicky Rode):

While a tsunami warning came to nothing, the quake damaged at least six
undersea telecommunication cables, affecting users in Taiwan and South
Korea, and was felt in China and Hong Kong.

And here's hinet taiwan's statement
http://www.cht.com.tw/CompanyCat.php?CatID=4&NewsID=1090&Page=HotNewsDetail
According to Chungwa, Sea-Me-We3 and APCN2 are affected.
Satellite connectivity is already being mentioned for
supplanting surviving regional connectivity.

Hi,
Information seems to suggest that these all have one or other faults due to the earthquake. Some probably have more serious problems then others.
SMW3 (Sea-me-we 3).
FNAL and FEA (FLAG North Asia Loop) ;
RNAL = Reach North Asia Loop
APCN2 (Asia Pacific Network 2)
C2C - Singtel's coast to coast
EAC = East Asia Crossing (EAC)
Traffic is gradually coming back through ad-hoc setups and re-routes, but cable providers are saying minimum 3 weeks for full recovery.
thanks
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.

Just to give you an idea:

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
