Submarine cable cut torpedoes Middle East access from the Register
A submarine cable in the Mediterranean was cut earlier today, resulting in a dramatic slowdown in internet access for people in India, Sri Lanka, Pakistan and much of the Middle East.
A spokesman for Flag Telecom, the owner of the severed cable, told the Reg: “It is a problem off the coast of Alexandria in Egypt. For some reason ships were asked to anchor in a different place to normal – 8.3km from the beach. One of the ship’s anchors cut our cable but there are multiple cuts – we’re not the only company having problems.”
Apart from being serious for the region, the cable break could also hit large UK and US enterprises which have offshored business processes and backoffice functions to companies in India, Pakistan or the Middle East.
