Really curious how _the quoted expert_ got "DDOS on core internet infrastructure" from this.

eNodeB or gNodeBs not broadcasting their networks would indicate a fault in the 4G/5G core (networks unique to each telco, not internet infra), which should be sufficiently isolated from the internet to not be DDoSable by random IoT devices.

This kind of fault would be more indicative of a configuration error, targeted attack, or external dependency. If the latter, I'm very curious who all of the major US telcos are depending on in that way...

Multiple networks being affected simultaneously would seem to rule that out, no?

That, to me, implies either an intrinsic fault (date/time related bug) or external factors, which could be as you've said a dependency (or hostile action.)

It wasn’t multiple networks it was AT&T.

Wondering if maybe someone got clever with SS7 or some other signaling protocol and found a way to DoS using it, seems like a dumb way to burn it so I am probably wrong and it will turn out to be some backend service everyone uses got popped.
