The third party Optus blamed for its network shutdown last week has been revealed as the telco’s parent company, Singtel.
On Monday Optus released a statement explaining the outage saying, “At around 4:05am Wednesday morning, the Optus network received changes to routing information from an international peering network following a routine software upgrade”.
Peering is a method that allows two networks to connect and exchange traffic directly without having a third party carry data across the internet – it is quicker and cheaper for customers.
The crucial Optus software upgrade that reportedly sent the wrong routing information to Optus happened at Singtel internet exchange.
During the upgrade, chaos erupted causing the system to overload and the network to shut down as a safety measure.
