Nearly 100,000 Optus customers in parts of Queensland have been hit by an outage impacting NBN services.
The telco confirmed the issue was impacting 95,000 customers in Brisbane and certain parts of the state today.
A network server failure at one of Optus' facilities in Rochedale, in the city's south, is believed to be to blame for the outage.

"We sincerely apologise for the disruption and thank customers for their patience while our teams work as quickly as possible to restore services," Optus said in a statement.
Mobiles are unaffected, but home phone calls via Optus NBN connections may be impacted if the customer has an older modem without 4G or 5G backup.
Optus has been unable to confirm whether triple zero calls were impacted by the outage.
It's not known when NBN connections will be fully restored.
Customers will need to turn their modems off and on again once the problem is fixed.
The outage is believed to be mostly affecting landline customers in Queensland.
However customers have reported internet access issues in areas including Robertson, Clifton Beach, Greenbank and in North Queensland, according to website DownDetector.
It follows a string of triple zero failures which have hit Optus customers over the past few months.
More to come.
