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: http://www.baltimoresun.com/technology/bal-bz.outage28dec28,0,7969015.story?coll=bal-technology-headlines 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.
