On 21 January 2016, at approximately 14:20, Akamai saw its traffic levels to South Africa suddenly dip by about 40%.
Traffic remained at reduced levels for about two hours.
Dyn Research noted that roughly 20% of network prefixes were down in South Africa as part of a larger set of outages throughout Africa.
According to African cable operator Seacom, these outages were due to construction activity in Egypt which led to multiple damaged Internet cables.
The disruption caused connectivity problems for the entire continent, as Seacom’s cables in and around Egypt provide connectivity for much of Africa to Europe, Asia, and the Middle East.
