Optus has acknowledged that it has experienced a distributed denial of service attack on its network link to the United States.
“Some Optus business Internet customers today experienced congestion to US destinations due to a technical issue with an international link carrying internet traffic,” an Optus spokesperson told Computerworld Australia.
The spokesperson said the issue began at 1.10pm and resulted in customers experiencing slow email traffic, slow web pages loading or time outs.
The issue was resolved at 3.25pm according to the spokesperson.
Users of ISP community website Whirlpool have been commenting on the issue, claiming that the outage was caused by a DDOS attack originating from China.
The Optus spokesperson confirmed that a DDoS attack was experienced, but that its origin was unknown.
The spokesperson apologised to Optus customers for any inconvenience.
