Akamai’s DDoS Mitigation Service Triggers Outages | Threatpost

Major financial institutions, airlines and the Hong Kong stock exchange were knocked offline by a backfiring distributed denial-of-service (DDoS) mitigation service Thursday. The hour-long outage, which was triggered at approximately 1 a.m. EST Thursday, is tied to Akamai Technology’s anti-DDoS Prolexic service.

In a statement to Threatpost at 7:44 a.m. EST, Akamai confirm a segment of its Prolexic platform was impacted and is now back up and running. “We are continuing to validate services. We will share more details of what transpired, but our first priority is ensuring all customer impact is mitigated,” wrote Chris Nicholson, senior public relations manager, Akamai.
According to reports, airline systems used by Delta, American, Southwest and United suffered outages at around 1 a.m. EST. Also impacted were financial institutions including Discover and Navy Federal Credit Union, according to a report by National Public Radio.

Australian based ITNews reported that services believed to rely on Akamai’s Prolexic were knocked temporarily offline.

“Users reported widespread problems accessing a range of internet properties and online services from the likes of CBA, Westpac, ANZ, UBank, AMP Bank, Macquarie Bank, ME Bank and more,” according to ITNews reporter Ry Crozier.

Mid-day operations of Hong Kong’s stock exchange were also impacted by the technical problems.

Virgin Australia also published a statement to its customers attributing an outage it suffered to Akamai’s Prolexic service.

“Virgin Australia was one of many organizations to experience an outage with the Akamai content delivery system today and we are working with them to ensure that necessary measures are taken to prevent these outages from reoccurring,” the airline said in a statement.

Akamai is aware of the issue and actively working to restore services as soon as possible.
