Still no root cause for Optus outage but government to review what happened

Optus is yet to make any new public statements regarding its total network collapse for over 8 hours yesterday, so we still don't have a root cause analysis. Matt Tett, "managing director of network analysis company Enex TestLab", speculates in the Guardian that "Optus are probably trying to pinpoint who is responsible and determine whether it is them or someone else" before giving a more detailed public statement. A Mastodon post by Rob Thomas outlines a theory that it was due to router upgrade gone wrong. Meanwhile, the Communications Minister announced a review of the incident, ACMA is looking into Optus' failure to comply with properly routing 000 calls, the Assistant Treasurer and Finance Minister wants Optus to compensate businesses and the Victorian government is "going to undertake its own review of both Optus' response and where we can see further improvements that can be made".
