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.
