SEA-ME-WE-4 Outage to Affect Internet and Telcom Traffic

The SEA-ME-WE 4 cable linking Europe with the Middle East and South Asia was cut on Wednesday, 14th April in the Mediterranean Sea.

It became inoperable due to a “shunt fault” approximately 1,886 kilometers from Alexandria towards Palermo, Italy in the S4 section of the cable.

A shunt fault occurs when the submarine cable insulation becomes damaged and a short circuit occurs when it comes into contact with water. While repairs are underway it is likely that the outage will take a further 4 days at a minimum and might take up to 10 days depending on weather and sea conditions.

Until today, SEA-ME-WE-4 was operating with limited capacity, however, today starting 12 PM Pakistan Time, all west bound traffic from Egypt onwards has been shut down.

Meaning that all traffic to Europe and US (from Pakistan) may face higher latency – but not the blackout due to redundant/alternate pipes available for usage. Though they cost extra to service providers because of shift of all traffic load to secondary pipes.

In a telephonic communication a Transworld official told ProPakistani that Transworld has bought additional capacity, worth millions of dollars, for eastbound routes, initially landing at Singapore via Japan to United States and then to Europe.

This will increase the route distance hence the latency, but traffic will not be impacted at large, said the official.

Transworld and PTCL are only operators selling international voice and data traffic in Pakistan.

Transworld, that is a sister concern of Mobilink and a project of Orascom has 40 percent market share in Pakistan for International traffic, with major operators such as Wateen, Worldcall, wi-tribe, Neyatel etc on its network.

    The dammaged occured on April 14, it didnt result in complete outage just partial. however, to repair it, the SMW4 cable was to be be taken down completely resulting in complete outage. this was planned for yesterday but it didnt happen because the Ship set out to carry the repair task at deep sea faced bad weather.

    This outage is still expected to take place when bad weather subsides and and the ship is ready to begin repairs.

    The Fault occured on 14th of April -2010. The traffic effected but the actuall maintainance window started from 24th April 2010 and it will end up by 28th April 2010 depending upone the conditions of see and other parameters. The Service providers aquired bandwidth via SMW3 to minimize the effect but will not be able to rule out the degradation in the service fully.

    extreme low speed :( nothing is working…

  • kashif

    PTCL DSL down for 3 days till 28th.
    PTCL service is extremely poor these days.

  • Furkan Awan

    Low Speed also Noted in WorldCall BroadBand Only during this current disturbance otherwise Worldcall is the best and Constant speed and constant downloading rate and it keeps constant or it may rise but i never seen such low connectivity for the past 8 months :(

  • StormPK

    i have heard that PTCL customers are facing severe congestion. PTCL has capped Internet capacity for Broadband to 50%. They may be doing this to reduce comaplaints from corporate and enterprise customers.
