Australian domain registrar and web host Melbourne IT has confirmed that an hour and a half-long service disruption suffered by its customers and its subsidiaries Netregistry and TPP Wholesale on Thursday was the result of a DDoS attack.
The attack on the company’s DNS servers affected a large number of national and international customers, the company says, disrupting cloud and cPanel web hosting, email platform, and access to the customer administration portal.
The incident began at 10 a.m. AEST Thursday, Melbourne IT said in an incident report. “In response, we implemented our DDoS mitigation services as standard operating procedure and implemented international traffic management measures. This returned normal service by 11:30am. This is now resolved and we are continuing to monitor the situation closely.”
Large-scale DDoS attacks, including on DNS networks, appear to be a growing trend, though Melbourne IT did not immediately share details of the attack.
Melbourne IT acquired Netregistry in 2014 for AU$50.4 million. Melbourne IT Group reported revenues of AU$168 million and net profit after tax of AU$10.7 million for fiscal 2016, a 91 percent profit increase from 2015. The company’s shares were trading for around AU$2.20 Thursday afternoon, after trading below AU$2.00 for most of 2016.
Melbourne sold its domain wholesale business OpenSRS to Tucows a year ago.
