  • •Internet disruptions expected from April 9 to April 13 due to submarine cable maintenance.
  • •SEA-ME-WE-5 cable maintenance will affect circuits to Singapore, causing slower speeds.
  • •SEA-ME-WE-4 cable will remain operational to minimize overall service impact.

Internet services across Bangladesh are expected to experience slower speeds and partial disruptions for approximately 80 hours from April 9 to April 13 due to scheduled maintenance on the SEA-ME-WE-5 submarine cable. The maintenance, which involves a shunt fault repair, will begin at 10 PM on April 9 and conclude at 6 AM on April 13. This work is being conducted by the Bangladesh Submarine Cables PLC and is expected to particularly affect circuits connected to Singapore. While the SEA-ME-WE-5 cable supplies around 1,488 Gbps of bandwidth, the SEA-ME-WE-4 cable will remain operational to mitigate the impact on internet services. Users may face slower internet speeds or intermittent service disruptions during this maintenance window. The total bandwidth consumption in Bangladesh currently exceeds 10,000 Gbps, making the maintenance critical for connectivity. The company has expressed regret for the inconvenience caused to users and stakeholders.
