The Australian Bureau of Statistics suffered four attacks during the week in the process of her five-yearly census. The census website was taken offline overnight on Tuesday.
The Bureau in a statement on their website mentioned that they took an abundance of caution by closing down the online Census form to protect data already submitted and the system from further incidents and minimize disruption on the Australian public of an unreliable service. They also confirmed that the disruption was not a hack and no data was compromised.
The attack is suspected to be launched from overseas and the site will be restored as soon as the necessary defenses are effected.
