Summary
- Over 90,000 Optus customers affected by server failure.

More than 90,000 Optus customers in Brisbane and surrounding Queensland areas are experiencing significant disruptions due to a network server failure. The outage, which commenced early Wednesday morning, has severely impacted NBN internet services for a large number of users.

The telecommunications provider initially assured that all services would be fully restored by 4pm on Wednesday, aiming to resolve the connectivity issues for affected NBN customers.
