Virtually all internet access in Egypt is cut off today as the government battles to contain the street protests that threaten to topple President Hosni Mubarak.
Organisations that track global internet access detected a collapse in traffic in to and out of Egypt at around 10.30GMT on Thursday night.The shut down involved the withdrawal of more than 3,500 Border Gateway Protocol (BGP) routes by Egyptian ISPs, according to Renesys, a networking firm. Only one ISP out of 10, Noor Data Networks, appeared largely unaffected. It connects to the outside world via an undersea cable operated by Telecom Italia.
According to BGPMon, another networking firm, 88 per cent of Egyptian internet access was successfully shut down, however.Renesys speculated that the apparent anomaly of Noor Data Networks may be a result of the fact it provides services to the Egyptian stock exchange.
