It will take a few days for the internet speed to return to normal

Internet bandwidth is down from Cox's Bazar to Singapore for maintenance of the country's first submarine cable SEA-ME-WW-4 in Chennai, India. Due to this, the speed of internet has decreased in the country. It will take at least 4 more days for the situation to normalize. During this period, BSCCL is providing Internet through alternative routes.
According to BSCCL sources, internet bandwidth supply from the country's first submarine cable for technical maintenance work is currently available at 80 to 90 Gbps instead of 250 Gbps. Bangladesh Submarine Cable Company Limited (BSCCL) said that this situation will continue till next Thursday. Internet data transmission from the cable's landing station in Cox's Bazar to Chennai, India has been suspended since May 18 for maintenance work. However, the capacity of the second submarine cable (SEA-ME-WW-5) has been increased to maintain the supply of bandwidth. At the same time, the bandwidth supply of the first submarine cable was put into operation on several alternative routes. 150 Gbps bandwidth is normally available from the second submarine cable. Now increased to 240 Gbps during emergencies. In total, BSCCL's two submarine cables are now delivering 320 to 330 Gbps of bandwidth. The current bandwidth capacity of BSCCL is 400 Gbps during normal hours. The daily internet bandwidth demand across the country is now 600 to 650 Gbps. The rest of the bandwidth demand is being met through ITC operators from India.
Bangladesh Submarine Cable Company Limited's (BSCCL) supply of bandwidth to the country through SEA-ME-WW-4 cable from Cox's Bazar to Geelong (the first submarine cable company's landing station) has dropped to one-third. Bandwidth (backup) is being provided through a second C-ME-5 cable. SEA-ME-WW-4 (South Asia-Middle East-Western Europe) consists of Singapore, Malaysia, Thailand, Bangladesh, India, Sri Lanka, United Arab Emirates, Pakistan, Saudi Arabia, Egypt, Italy, Tunisia, Algeria and France. SIMUI-5 is owned by Singapore, Malaysia, Thailand, India, Pakistan, United Arab Emirates, Saudi Arabia and some European countries. These 16 countries also own the second submarine cable.
Moshiur Rahman, Managing Director of BSCCL, said that the work of changing a repeater of C-Me SEA-ME-WW-4 cable started in Chennai from last May 18. Due to this the Cox's Bazar-Chennai-Singapore route is closed. However, while the western part of the cable is closed, some bandwidth is available through the eastern part. The cable is not closed at all. The cable is expected to be back to normal by Thursday. BSCCL has put in place alternative arrangements on the Cox's Bazar-Bangkok-Singapore route. Similarly, the situation is being controlled by increasing the capacity of the second submarine cable. In addition, six International Territorial Cables (ITCs) are operational to bring bandwidth from India overland. As a result, bandwidth is not a problem in the country. But some less bandwidth is available than required.
