RE: txt.att.net outage?

["Simmons, Jay via NANOG" <nanog () nanog org>]

This may be the issue

Here are some details on this Government protocol implemented by all Telecom Carriers.

Why it is being done? To support FCC mandate for STIR/SHAKEN, an industry set of rules designed to authenticate and 
validate CallerID information associated with phone calls using digital signatures.

SHAKEN/STIR is a framework of interconnected standards. SHAKEN/STIR are acronyms for Signature-based Handling of 
Asserted Information Using tokens (SHAKEN) and the Secure Telephone Identity Revisited (STIR) standards.

What is the benefit to the clients being impacted (what do they get as a result)? Provide a means to mitigate/eliminate 
illegally spoofed calls from RoboCallers.

EXTERNAL EMAIL
FWIW, AT&T does not suggest using the txt.att.net<http://txt.att.net> email for anything critical. In a previous role I 
handled public safety CAD, and AT&T (and Verizon, if I remember correctly) made it very clear that if you want to be 
able to send anything other than a miniscule volume of texts through the email-to-SMS gateway, you would need to pay 
for their enterprise messaging service.

If the public safety agency/agencies in question subscribe to the FirstNet service, they should be able to reach out to 
their principal consultant (account team) and get a good resolution.

Know this is a longshot, any chance anyone from the txt.att.net<http://txt.att.net> domain might be able to help us 
with what we believe is a blacklist block or possibly an outage?

We deal with 911 cad dispatching and is affecting first responders so looking to see if there is a faster way to 
resolution.



Thanks, in advance.
