Is this more widespread than Palo Alto 911? Is it affecting AT&T phonelines generally, and is it affecting other911 calls outside Palo Alto?

Hopefully everything will be up and running very soon.

More major infrastructure break downs. This is not okay.

Isn't AT&T the company that got the huge contract for Palo Alto's pricey Fiber To The Home project, the one where the city survey gave no option for saying we didn't want it and instead solicited advanced deposits?

Isn't AT&T the company whose Palo Alto customers recently suffered 4 days - FOUR days -- of total internet outage and whose customer service failed to respond to questions from individual customers and distribution partners like the usually reliable Sonic?

Why yes, AT&T is that company.

“Once that was re-established, there were other technical issues that still needed to be resolved on the Palo Alto side of the connection inside the dispatch center to fully restore service,” the update stated.

How long did it take before someone on the city side realized that when an external outage occurs, it puts the delivery side of things in a "not ready" state? Meaning it needs to be re-booted?

Just waiting until PA starts providing their usual level of "customer service" for its $$$,$$$,$$$ Fiber to the Home endeavor and they get a clue about customer expectations.
