The overnight television ratings are unavailable again, with Nielsen confirming the disruption is a result of a ransomware attack.
Both Nielsen and OzTAM stressed that households are still collecting their viewing data, and that referencing sites have not been impacted.
Yesterday, the delay was attributed to “an unexpected disruption” relating to Nielsen’s “Australian TV Audience Measurement (TAM) data centre environment”.

Nielsen said it was working on the issue.
“Nielsen’s global and local infrastructure teams took the steps to contain the incident, launched a robust investigation and are currently working to resolve the issue as fast as possible. We will be sure to keep the industry informed as new information on the matter becomes available,” a spokesperson said.
It’s understood the data will be made available once the issue is resolved.
