Kenapalah hari ni (22 ogos) internet semakin selow...??



rupanya ada maintanance dari 12.00am sampai 6.00 am

Internet services will not be fully restored until end of Jan (maybe....)

A 7.1-magnitude earthquake just south of Taiwan knocked an unprecedented seven submarine communications cables out of service on 26 December, impairing international communications to Taiwan, Japan, Hong Kong, China, Korea, and Malaysia.

Many observers have speculated that the cable outage has been exacerbated by a lack of investment in Asian cable infrastructure, or by Asian network capacity constraints. TeleGeography’s Submarine Cable Map 2007 dispels this myth: a diverse array of undersea cables connect the countries of Asia to one another and to the world. In the past year, three of these cable systems, Asia Netcom’s EAC, FLAG and REACH’s North Asia Loop and the APCN-2 consortium cable upgraded their networks’ capacity, in order to accommodate growing traffic volumes. However, even after these upgrades, most intra-Asian systems are operating at less than 15% of their potential capacities, leaving plenty of room for future traffic growth.

Sources with China Netcom (CNC) said seven repair ships have been working round-the-clock, but the nature of the undersea terrain and bad weather had combined to slow work. To make matters worse, the extent of the damage to the cables was initially underestimated......
China Telecom said another reason for the delay was the dense and intricate distribution of trans-oceanic networks in the area off Taiwan. It said the most optimistic estimation for resumption of full services is Jan. 20.



What steps can be taken to protect against future network outages in Asia?

The upcoming deployment of new cables, such as the Trans Pacific Express and Asia American Gateway, will provide new routing options, helping to improve networks’ resiliency. While many buyers already purchase capacity on multiple cable systems to provide redundant capacity, network operators may procure capacity on an even more diverse array of cable systems in earthquake prone regions, and deploy fault-tolerant mesh networking technologies over these cables.

Finally, these outages may increase interest in routing more capacity from Asia and Europe over the trans-Russia networks of Rostelecom and TransTeleCom. Once again, my apologies for the size of the map but it is important if only to give you a feeling of security.

Repairing cable still going

by Dr Mohamed b. Awang Lah

Saturday, 06 January 2007 10:11 AM

In any crisis such as the current one, we always look forward to receive frequent updates from the service providers or cable operators. We can see clearly who are actually caring and responsive and who could not care less. After eight (8) days, one service provider is still checking the agreement to find out whether or not certain circuit is supposed to be restored! Many similar operators prefer to keep mum and compel everyone to play the guessing game on the work progress. Fortunately, at least one operator never fails to give daily updates. It gives detailed description (including names) of the ships being dispatched to the affected site and the estimated time for every step of the restoration process. One ship actually encountered problem while attempting to repair a cable. The ship itself has to be repaired first – causing more delay to the restoration job. Anyway, I wish service providers in Malaysia emulate such culture of transparency. At this point we know that at least eight (8) major cables have been damaged caused by the earthquake. These are: APCN – Asia Pacific Cable Network – 10 Gbps APCN2 (2 faults) – 160 Gbps (maximum 2.56 Tbps) FNAL (2 faults) – FLAG North Asia Loop – 160 Gbps (maximum 2.4 Tbps) FEA – FLAG Europe Asia – 10 Gbps China-US (2 faults) – 80 Gbps EAC (4 faults) – East Asia Crossing – 120 Gbps SMW3 (2 faults) – South East Asia-Middle East-Western Europe – 70 Gbps C2C (3 faults) – 160 Gbps (maximum 7.68 Tbps) (Gbps = gigabits per second, Tbps = terabits per second) Many ships are involved in the restoration works. The estimated dates to restore differ for different cables starting from 7 January 2007. So far the best estimate for a complete restoration of the damaged cables is mid February 2007. JARING service is now running at approximately 70% of the normal capacity. As optimisation is being done, we see continuous improvement by each day. Full recovery is expected by mid January. We are grateful for the patience shown by our subscribers and we thank them for their understanding for bearing with us during this trying moment. Dr Mohamed b. Awang Lah is the Chief Executive Officer of Jaring

Gegaran di barat daya Taiwan rosakkan kabel dasar laut APCN2

KUALA LUMPUR: Perkhidmatan internet antarabangsa termasuk di Malaysia mengalami gangguan teruk apabila kabel dasar laut Asia Pasifik Rangkaian 2 (APCN2) terputus ekoran gempa bumi di barat daya Taiwan, kelmarin.

Berikutan itu, lebih 3.8 juta pelanggan internet di negara ini mengalami kesukaran melayari laman web yang berpangkalan di luar negara, terutama Amerika Syarikat (AS), Jepun, China, Taiwan, Korea Selatan dan Eropah.

Kerosakan kabel di persisiran pantai selatan Taiwan itu turut mengganggu 98 peratus daripada kapasiti perkhidmatan telefon kepulauan itu dengan Malaysia, Singapura, Thailand dan Hong Kong.

Telekom Malaysia Bhd (TM), dalam kenyataan semalam berkata gempa bumi di Taiwan itu mengakibatkan kerosakan sistem kabel dasar laut termasuk APCN, APCN2, SEA-ME-WE3, CUCN dan FLAG.

Kerosakan itu menyebabkan perkhidmatan panggilan antarabangsa ke Taiwan, Jepun, China, Hong Kong, Korea dan Amerika Syarikat terjejas.

"TM sedang bekerjasama dengan ahli konsortium untuk melaksanakan kerja membaik pulih. Bagaimanapun, setakat ini, konsortium masih tidak dapat menentukan tempoh masa untuk perkhidmatan pulih sepenuhnya," katanya.

Syarikat itu menasihatkan pelanggan yang ingin membuat panggilan antarabangsa supaya menghubungi perkhidmatan bantuan operator TM di talian 101.

TM Net Sdn Bhd pula memaklumkan, perkhidmatan internetnya mengalami gangguan prestasi berikutan sambungan talian sesak dan melampau di beberapa jaringan internet antarabangsa semalam.

Dalam kenyataannya, syarikat itu berkata ia sudah mengambil tindakan segera dengan mengalih laluan trafik ke jaringan sokongan lain bagi mengurangkan kesesakan.

"Pengguna internet di Malaysia dan bahagian lain di negara ini mungkin mengalami sedikit penangguhan dalam mengakses kandungan laman web berpangkalan di luar negara, terutama di AS, Jepun, China, Taiwan, Korea Selatan dan Eropah," katanya.

TM Net menjelaskan, gempa bumi berukuran 6.7 pada skala Richter di pantai selatan Taiwan malam kelmarin menyebabkan gangguan pada kabel APCN2 antara Shantou, China dan Tanshui, Taiwan serta Lantau, Hong Kong dan Chongming, China.

"Ia menyebabkan sambungan internet yang melampau pada talian internet TM Net International secara sambungan transit atau pemula, terutama ke negara yang disebutkan," katanya.

Pelanggan boleh menghubungi Pusat Interaksi Pelanggan TM Net di 1-300-88-9515 (24 jam) atau 1-300-88-1515 dari 8 pagi hingga tengah malam atau e-mel ke custcare@tm.net.my untuk pertanyaan lanjut.

JARING Communications Sdn Bhd pula berkata talian antarabangsa syarikat itu turut terjejas bermula jam 3.46 pagi semalam dan ia sedang berurusan dengan pihak pembekal talian antarabangsa untuk menyegerakan proses membaik pulih.

"Bagaimanapun, jangka masa proses untuk mengembalikan operasi talian itu tidak dapat ditentukan lagi," kata Pusat Operasi Rangkaian JARING dalam kenyataan di laman webnya.

Gangguan perkhidmatan internet juga menyebabkan sebahagian besar pengusaha kafe siber menutup perniagaan, manakala pengguna internet syarikat korporat gagal menghantar emel atau melayari laman web.

Ketua Komunikasi Korporat Suruhanjaya Komunikasi dan Multimedia (SKMM), Adelina Iskandar, ketika dihubungi berkata, pihaknya meningkatkan pemantauan dan menunggu laporan TM Net dan JARING sebelum mengambil tindakan lanjut. TM Net mempunyai 2.85 juta pelanggan manakala JARING lebih sejuta.

Gempa bumi di pantai bandar Hengchun berhampiran selatan Taiwan itu berlaku pada hari ulang tahun kedua bencana tsunami yang meragut lebih 200,000 nyawa di selatan Asia.

Dalam kejadian kelmarin, dua sekeluarga dilaporkan maut apabila rumah mereka di bangunan empat tingkat runtuh manakala enam sekeluarga diselamatkan awal semalam.

Sementara itu, agensi berita AFP memetik penganalisis sebagai berkata, sistem telekomunikasi antarabangsa ketika ini menggunakan kabel dasar laut yang menyambungkan rangkaian hubungan antara negara di seluruh dunia bernilai berbilion dolar.

Penganalisis telekomunikasi bebas, Paul Budde berkata, laporan awal mendapati kabel dasar laut itu ditanam sejak 150 tahun lalu untuk penghantaran telegram dan kini berkembang sebagai talian internet bagi menepati kehendak teknologi semasa.

Di TAIPEI, Naib Pengurus Besar Chunghwa Telecom Co, Lin Jen-hung.

Syarikat telefon terbesar Taiwan itu berkata, kerosakan kabel itu menyebabkan talian telefon dan perkhidmatan internet terganggu ke beberapa bahagian di China, Korea Selatan, Jepun, Asia Tenggara dan AS.

Beliau yang dipetik AP berkata, usaha memperbaiki kabel itu mengambil masa sehingga tiga minggu tetapi 'kualiti akan bertambah baik dari sehari ke sehari.

Syarikat telefon terbesar Taiwan itu berkata, kerosakan pada kabel di persisiran pantai selatan Taiwan itu turut menjejaskan perkhidmatan internet bagi sebahagian pengguna di Hong Kong yang tidak boleh melayari laman web di sebahagian kawasan di Asia dan AS.

Syarikat telefon Hong Kong, PCCW Ltd, yang turut menyediakan perkhidmatan internet, berkata beberapa kabel data di bawah laut rosak dalam gempa bumi itu.

"Perjalanan data ke Taiwan, Korea, Jepun dan AS terjejas," kata PCCW dalam satu kenyataan.

Syarikat berkenaan juga memberi amaran kepada pengguna bahawa mereka mungkin mengalami kesesakan selama beberapa hari di internet kerana peningkatan penggunaan oleh ramai orang yang melayari laman web untuk mendapatkan maklumat mengenai gempa bumi itu.

Pedagang mata wang di Hong Kong - salah satu pusat perniagaan terbesar Asia, mengadu mereka hilang hubungan dengan Bloomberg LP, pembekal utama berita dan data mengenai pasaran saham.

Internet terputus atau amat lembap di Beijing, kata pegawai dari China Netcom, syarikat telefon kedua terbesar di China.

Perniagaan di beberapa bahagian lain bandar raya itu juga mengalami masalah melayari internet manakala rangkaian televisyen kerajaan, CCTV, melaporkan gempa bumi itu merosakkan kabel komunikasi bawah laut dari China ke AS dan dari Asia ke Eropah.

Ia berkata, syarikat telefon terbesar China, China Telecom Corp, menghubungi syarikat sejawatnya di AS dan Eropah untuk mencadangkan penggunaan satelit.
