I would expect that some of the affected cables have lost dc power used to =

repeaters and amplifiers (10 kv d.c.) from their landing stations. Or that =

[FAC: Assuming the link below works, the article below contains an excellent
global view of what looks like most, if not all, of the major submarine cab=

routes around the world in use today. It's a keeper, IMO, so I suggest
downloading it to your HD. Here's the pdf, which is probably subject to the=

BEIJING -- A big earthquake near Taiwan disrupted phone and Internet traffic
across Asia Wednesday, highlighting the fragility of a global telecommunica=
tions
system that still relies on vulnerable undersea cables to carry data.
The magnitude 6.7 temblor that struck late Tuesday off Taiwan's southern co=
ast
cut several fiber-optic cables that carry communications traffic through a =
key
nexus in Asia, connecting Hong Kong and Southeast Asia with Japan and,
ultimately, North America.
