[NNagain] Cellular outage in US hits AT&T, T-Mobile and Verizon users, Downdetector shows + Cyberattacks on hospitals are likely to increase, putting lives at risk, experts warn

[Bill Woodcock]

I have not seen any credible evidence of any networks other than AT&T being involved.  

The rumors of something to do with a SIM database don’t explain all the PRI trunks down, but those predated the mobile outages, so it might be two unrelated issues.
