The network later saidits team was frantically working to fix the morning's technical issues and its usual shows of Weekend Today and Sports Sunday would not go to air.
The channel aired prerecorded programmes until at least 1pm to give them time to fix the technical issues.
Our teams are working to fix this morning’s technical issues and will return to normal broadcasts as soon as possible. In the meantime, today’s programming changes for @Channel9:
9.00am Taronga 10.00am The Sunday Footy Show 12.00pm Tipping Point 1.00pm Women’s Footy https://t.co/q86KrYcMRQ
Sources told TV Blackbox that the problems were nationwide and had hit live programming across Australia.
The technical issues also mean the network had been unable to prep each programme, throwing the channel's 6pm news bulletin into question.
However, a spokesperson for Nine said the network would be resuming live programming soon.
"Nine is responding to technical issues affecting live broadcasting. At this stage we are working through the impacts across the network and will provide an update as we resolve the systems," the spokesperson said.
