DDOS takes down Cirrus Communications

Australian fixed wireless provider loses half its network for a day or so

Choosing a cloud hosting partner with confidence

Fixed wireless broadband provider Cirrus Communications has experienced a distributed denial of service (DDOS) attack that incapacitated half its network.

Cirrus provides wireless networks to business, apartment complexes, residential colleges and military bases. The company says it is a last mile provider and prides itself on “competitive pricing … in metropolitan data centres to remote or broadband constrained areas,” an “ability to deliver high bandwidth where organisations need it” and an “Its ability to connect multiple locations for organisations on a breakthrough economic basis.”

But over the last day, those services have not been available to all customers, as CEO Eric Heyde told The Register the company yesterday experienced a DDOS attack that took down “more than 50 per cent” of its network and that it experienced "struggles" in the wake of the event.

“We are very close to full recovery,” Heyde told The Reg. “We've only got a couple of per cent of the network down at present.” [15:30 AEST - Ed]

Heyde said the attack hit Cirrus' core network, rather than the radio equipment on the edge.

“It's too early to say where the attack came from,” he added, and declined to offer further comment on the attack's origins.

Reg readers have suggested the attack has disrupted communications to other carriers that use Cirrus' services. ®
