That requires cell coverage. That requires the person to be capable of receiving the alert at the time (not engrossed in a TV show or game). If the mobile wireless networks were sufficient, this whole proceeding wouldn't be needed. ----- Mike Hammett Intelligent Computing Solutions Midwest Internet Exchange The Brothers WISP ----- Original Message ----- From: "Richard Porter" <richard@pedantictheory.com> To: "NANOG list" <nanog@nanog.org> Sent: Monday, January 4, 2021 10:40:28 PM Subject: Re: NDAA passed: Internet and Online Streaming Services Emergency Alert Study On Mon, Jan 4, 2021 at 10:25 PM Chris Adams < cma@cmadams.net > wrote: Once upon a time, Billy Crook < BCrook@unrealservers.net > said:
On a technical note (having read the comment about overloading the system) could a system like DNS help handle this?
I wouldn't think so, because some of the important alerts are very time sensitive. It's been mentioned several times in this thread that the earthquake alerts are on the order of 10 seconds in advance. I know someone that survived a tornado by a few seconds (the time it took to get out of bed and get to the bedroom door as the tornado dropped the second floor of the house on the bed). 4G/LTE/5G networks could be further leveraged for this. In Denton County, TX, USA, you can register to "opt in" to receive weather alerts. We get tornadoes here. I could see better leveraging of that technology than streaming services. It is uncommon to find anyone without a cell phone in the US anymore. EMS services in some states leverage private 3G/4G networks for real-time communications. Wider reach in population clusters. <blockquote> To be useful for the worst events, they need to be push, and push in very short order. And since those are the alerts most likely to be life-saving, those are what the system needs to be built for (or what's the point). And to the point of the weather service sending out more alerts than in the past: yes, they do. To some extent, it's better radars and software to find hazards; they're also learning all the time to better identify what is and is not a threat (so there are storms that might have had a warning 10 years ago that might not today). But I'll take extra alerts now and then... a friend died in a tornado years ago because the warning came after it was on the ground (and probably after they were dead). -- Chris Adams < cma@cmadams.net > </blockquote>
