npub17lgy0rj5a2nwpnyc4hup6ufpfz7wz6dzcgd3crm6fm2yd34dcz0qlk9uux (npub17lg…9uux) Losing the RAN is not that bad. You don't want a massive outage and the RAN saying all's well, because then 000 is 'available' but can't complete calls, whereas otherwise the handset can select an operating carrier for emergency calls.
So as long as no truck rolls are required, the RAN is a second-order issue.
Optus's primary issue is likely lack of tooling to visualise where the routes hammering them are entering their core network. Couple that with some lax filtering and it can be hard to get any network back.
Cyber-stuff is, in general, quite obvious in the attack phase. There have been some slow drawn-out BGP-based attacks, but they are rare. It's likely at this stage the the cyber people are getting underfoot, not helping.
