- In short: Optus says close to 2,700 customers tried and failed to call emergency services from their mobile phones during the November 2023 network outage.
- This number is more than 10 times higher than what the telco previously told the Senate.
- What’s next? Optus says it is writing to each customer individually to apologise, and the federal government is conducting a post-incident review.
Any comment I made on the cause of the incident would be pure speculation, but I’d be astonished if it were something so trivial. I suspect it more likely to be through some unknown hardware bug that didn’t happen in the Dev/Test environments for some reason. From what they have told the Senate Committee, this was a routine update. Those don’t usually carry significant risk of failure.
So all we do know for real is that it was very unexpected and complicated to fix. Something minor like you are describing would not generally take 10 hours to roll back.
