In a major blow to the commercial TV networks, OzTam is set to lose the missing ratings information after redundancy back-ups start recording over the data.
The television industry has been on tenterhooks after being advised last Wednesday that ratings data would be delayed due to an ‘unexpected disruption’, affecting data for Tuesday July 21 onwards.
At the time OzTam issued this statement:
Nielsen has advised OzTAM of an unexpected disruption relating to their Australian TV Audience Measurement (TAM) data centre environment.
Tuesday’s TV viewing data will be collected and processed once functionality is restored.
This means that overnight data for Tuesday (July 21) will be delayed.
Nielsen is working to resolve this matter swiftly and is keeping us informed. OzTAM will forward Tuesday’s ratings reports when available.
Thanks for your patience,
As TV Blackbox confirmed, the delay was due to a ransomware attack on the servers Nielsen uses to collect the data (Nielsen is employed by OzTam to collect the data).
A rep for Nielsen told us:
Nielsen has become aware of an unexpected disruption relating to the Australian TV Audience Measurement (TAM) data centre environment. This disruption is derived from a ransomware attack in which Nielsen was the victim.
As a result, TV ratings data remains unavailable. Nielsen can confirm, however, that all households are still collecting viewing data and that referencing sites have not been impacted.
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.
While it is true “that all households are still collecting viewing data”, TV Blackbox can reveal that data is only stored for 7 days. This means that if OzTam and Nielsen cannot retrieve the data by Tuesday, ratings for that day will be lost, and if it stretches into subsequent days more data will go missing including the all-important the Big Brother finale data for Channel 7.
When TV Blackbox reached out for clarification on the issue of ratings data being recorded over, we were told:
Given the sensitivity of the matter, we’re unable to add to previous statements at this stage. We’re working hard to restore and resume the TV ratings service and will share more information when we can.
But in an interview from 2016 OzTAM chief Doug Peiffer confirmed ratings data is only stored on the devices in houses for seven days:
“The meters will store the information for up to seven days, so we can always get that data back and not miss anything.”
Obviously this is an unprecedented event and there is no doubt a situation was never envisioned where the data wouldn’t be able to be retrieved beyond seven days.
But considering millions of dollars in revenue can swap hands based on ratings data, this is a very trying time for each of the commercial networks hoping to lure in advertisers with successful shows, especially Channel 7.
If this problem is not sorted out soon we will be in uncharted territory, – a world without ratings is a very strange world indeed.
