The census website was restored at 2:30 pm on 11 August. On the same day, Prime Minister Malcolm Turnbull stated his displeasure over the event, which had "been a failure of the ABS", with his expectation that "heads will roll" once a review was complete. Leader of the opposition Bill Shorten said that the 2016 census had been the "worst-run ... in the history of Australia". The ABS blamed service provider IBM for the failure in the online census, saying that IBM had advised on the preparedness and resilience to DDoS attacks and had not offered any further protections that could be employed. On 31 August, the Parliament of Australia initiated an inquiry into the 2016 census. It released its findings on 24 November: no individual party was found to be responsible but it was shared between the government, IBM, and other sub-contractors.
