The peering network that contributed to the Optus outage last week has been revealed as its Singapore-based parent company Singtel.
On Monday Optus released a statement explaining the meltdown saying, “At around 4.05 am Wednesday morning, the Optus network received changed 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.
The crucial software upgrade that reportedly sent the wrong information to Optus happened at the Sintel internet exchange.
Ten million Australians were impacted by the Optus blackout – which took 16 hours to resolve.
