The outage apparently began 4am AEDT. It's now 11am. For 7 hours and counting - no network at all in large parts of the country including no mobile network at all (if not all - I haven't heard of anywhere where it is working fine).
The impact is huge. As others have mentioned it's impacting financial services networks and in Melbourne, it's impacting the Metro train network (they use Optus for their backup communications).
The very widespread nature makes me think "there's gotta be more than one failure here" e.g. can't just be a DNS issue. Follow up thought - "could this be a non-accident?" i.e. a deliberate outage on behalf of actors unknown?
- YPPH 3y agoMost likely related to BGP, they probably made an erroneous change leading to routing errors. These things are hard to fix and have been known to happen in big tech. You can see a flood of BGP announcements the time it started: https://radar.cloudflare.com/as4804?dateRange=2d https://radar.cloudflare.com/as4804?dateRange=2d
- FLT8 3y agoThe 4am start time kind of makes it sound like a scheduled change gone wrong. Maybe so wrong that they lost access to the control plane and needed to send engineers on-site to fix? I think if it had been malicious we would have heard about it by now..
