Telstra outage: one GPS card reset the network to 2006
A July 8, 2026 Telstra outage hit nearly 9 million customers after a GPS card in a Melbourne NTP chassis rebooted and reported November 2006 due to a missing GPS week-rollover fix. The external TAP report was published September 2; Telstra faces a possible fine of up to $30 million.
- Outage affected 45% of calls and data sessions and 604 Triple Zero calls
- The card came up 1,024 weeks in the past — November 2006 — due to old firmware
- A 2020 switch to NTP peering left no source able to outvote the faulty clock
- Telstra moved all three sites off the old servers; fine could reach $30 million
