txt.att.net outage?

Fri Jan 20 14:24:31 UTC 2023

txt.att.net <http://txt.att.net> is returning MX records and those machines don't have port 444 open...

Wouldn't you want to be sending something like a SNPP message instead? It's a much less convoluted delivery process and is almost real-time (no queuing).

I guess it's been a decade or so since I've dealt with emergency services and paging...is SNPP even a thing anymore?

I looked at some old code I wrote (https://github.com/darkpixel/snppsend/blob/master/more-providers <https://github.com/darkpixel/snppsend/blob/master/more-providers>), and it doesn't look like snpp.attws.net <http://snpp.attws.net> exists.
