AT&T inter-carrier problems in the USA today - AT&T nation-wide issues calling users on other carriers.. 911 impacts.. FCC investigating. I'll have some general comments on this USA based failure event and other recent US and Canadian carrier outages coming in my upcoming whitepaper on PSBN policy alternatives for Canada's 911 and First Responder telecommunications systems. Per Downdetector.com it seems like today's AT&T failure event had a ~7hr outage from ~12:00PM to ~7:45PM Eastern Time. Some confusion was reported regarding 911 calling due to faulty SMS texts during the event erroneously claiming that 911 dialing was impacted. Also concerning, some 911 First Responder agencies with FirstNet were also apparently impacted by these AT&T problems - such as this Kansas City-area Sheriffs Office noted in this article.. https://lnkd.in/gB2jSHsm NBC News Article Quote.. "...The disruption occurred a little more than three months after a widespread outage affected AT&T customers, leaving people without service. During that incident, around 50,000 outages were reported at one point. The company said then that problem was caused by a process error. The website Downdetector noted a spike in reported outages for both AT&T and Verizon on Tuesday. T-Mobile said it was not experiencing an outage, but the problems with other carriers might impact its customers trying to connect to other networks." #multicarrier #PSBN #policyalternatives #gracefulfailuremodes #CRTC #ISED #telecommunications #Canada #Ontario #networkofnetworks #lessonslearned #onesizedoesntfitall #alleggsinonebasket #thefutureisnow https://lnkd.in/gwpgA2FG
