Update: Connectivity to affected sites has been restored.
A large DDoS attack in the US against a company which runs managed DNS services is causing multiple major websites to go offline – including those with a presence in South Africa.
PayPal, Twitter, Sony PlayStation Network, and eBay were not available in South Africa at the time of writing, following reports from the US that Dyn’s managed DNS infrastructure was under a sustained DDoS attack.
According to the Independent, Twitter, Netflix, PayPal, eBay, PlayStation Network, and Amazon all suffered downtime in the US.
At the time of writing, Netflix’s smart TV app was working when tested by MyBroadband. The desktop site was live, but videos were slow to load.
Google and Facebook have not suffered any downtime, according to the report.
Dyn said its engineers were monitoring the attack and attempting to mitigate it. The size and origin of the DDoS attack has not yet been reported.
Ars Technica reported that Dyn suffered an initial DDoS attack on the morning of 21 October, which it mitigated. The attack was “a global DDoS attack on [Dyn’s] Managed DNS infrastructure in the east coast of the United States”.
A second attack then followed a few hours later, which Dyn said may impact Managed DNS advanced services.
