Rekan Mediacare, kesulitan akses internet? Penyebab kesulitan akses
internet di Indonesia adalah gempa di Taiwan yg merusak jaringan serat
optik bawah laut yg menghubungkan Taiwan dg Amerika. Kerusakan akibat
gempa meliputi kabel2 cadangan. 

Tingkat putusnya hub internet: 70% jaringan internet di Jepang dan 90%
jaringan internet di Asia Tenggara. Bayangkan kesulitan yg dihadapi
oleh mereka yg sistem kerjanya tergantung internet, termasuk beberapa
perguruan tinggi di Singapura dan Malaysia, maskapai2 penerbangan,
selain perusahaan2 e-commerce dan e-business. Copy berita ada di bawah
setelah komentar saya ini.

AFAIK, infrastruktur jaringan ihternet di seluruh dunia sekarang
adalah infrastruktur yg awalnya dirintis oleh beberapa perguruan
tinggi di Amerika dan diadopsi untuk dikembangkan ke seluruh dunia.
Sekitar tahun 1992, saya yg waktu itu sedang kuliah di Amerika
beruntung di ajak seorang teman untuk gabung di sebuah prototype
mailing-list. 

Prototype mailing-list tsb mrpk salah satu hasil awal dari
pengembangan awal internet di masa perintisan jaringan internet. Masa
itu, jaringan internet yg awalnya diuji-coba di satu dua PT di
California, kemudian dikembangkan sebagai alat komunikasi antar PT2 di
Amerika dan PT2 di beberapa negara maju lain (mohon dikoreksi jika
salah). Walaupun demikian, chairman dari jurusan di fakultas tempat
saya kuliah sudah mengumumkan bahwa masa depan kantor jurusan adalah
'a paperless office'. 

Barangkali sampai jaringan internet di Indonesia pulih 100%, saya dan
sedikit teman2 di LN 'ngomong sendirian' di mailing list ini yg untuk
sementara susah diakses dari Indonesia. Saya dengar dibutuhkan waktu
sekitar 2 bulan untuk bisa 100% pulih. Dari sekian banyak berita ttg
hal ini (termasuk dari TV), saya copy berita dari URL:

Salam.

TAIPEI, Taiwan //  With one blow, Mother Nature triggered the largest
telecommunications outage in years, cutting off or slowing telephone
and Internet traffic in Asia from Beijing to Bangkok, Thailand.

A powerful earthquake off the southern tip of Taiwan late Tuesday
damaged up to a dozen fiber-optic cables that cross the ocean floor
south of Taiwan. They usually carry traffic between China, Japan,
Korea, Southeast Asia, the U.S. and the island itself.

The magnitude-6.7 tremor, which struck near the town of Hengchun,
killed two people and injured more than 40.

Chunghwa Telecom Co., Taiwan's largest phone company, said the quake
damaged several of the cables, and repairs could take two to three weeks.

Taiwan lost almost all of its telephone capacity to Japan and mainland
China. Service to the United States also was hard hit, with 60 percent
of capacity lost.

Later, Chunghwa said connections to the U.S., China and Canada were
mostly restored, but 70 percent of the capacity to Japan was down,
along with 90 percent of the capacity to Southeast Asia.

Stephan Beckert, an analyst with the Washington-based research firm
TeleGeography, said it was the largest telecommunications failure in
years.

"The magnitude of the break is surprising because Taiwan is otherwise
a very well-connected system," Beckert said.

He said cables get cut and disrupted all the time, but there's usually
enough backup capacity on other lines to keep traffic flowing without
customers noticing an interruption.

But with multiple cables broken, Internet traffic around the Pacific
was disrupted. Hong Kong telephone company PCCW Ltd., which also
provides Internet service, said the quake cut its data capacity in half.

Internet access was cut or severely slowed in Beijing, said an
official from China Netcom, China's No. 2 phone company.

The Internet Traffic Report Web site, which monitors Internet
connectivity in several countries, showed that packet loss, or the
percentage of data that doesn't reach its destination, spiked sharply
in Asia at the time of the earthquake, rising from about 10 percent to
more than 40 percent.

By yesterday afternoon U.S. time, the Web site showed limited
connectivity to China, Singapore and Indonesia, while Japan and Taiwan
were apparently back to normal.

KDDI Corp., Japan's major carrier for international calls, said its
fixed-line telephone service was affected by the quake. Spokesman
Haruhiko Maeda said customers were having trouble calling India and
the Middle East, which usually use the cables near Taiwan. Maeda said
the company was rerouting calls through the U.S. and Europe.

In the U.S., Cisco Systems Inc.'s Linksys unit said customer-support
call centers for its home networking gear were affected by the outage.
