Description:
The US cellular network just experienced its biggest outage in recent memory. What happened, and what does it mean?

FULL STORY ======================================================================

If you didn't get that call or text you were expecting today, and you live in the US, it may not be your fault. AT&T, and possibly the other two major carriers in the US T-Mobile and Verizon experienced on Thursday an hours-long outage that, as of this writing, is ongoing (but may be quickly winding down).

And by outage, we mean no cell service at all for tens of thousands of customers, mostly AT&T ones, in multiple states. I learned about it early
this morning via a text from a television news network. The producer asked if I'd heard about this big network outage. I hadn't, and joked that apparently Verizon wasn't affected because, well, we were talking and texting on their network.

After the call, I opened DownDetector , a decent online gauge of almost any online and network service's current health. It does not tap into these networks, and instead relies on real-time customer reports. Even so, DownDetector painted an alarming picture. At approximately 4am ET, all the major networks experienced a huge spike in outage reports. That bled into smaller networks, which use the big guys' network infrastructure, and which were also getting outage reports.

As I visited the AT&T, Verizon, and T-Mobile websites I noticed there were no alerts just more pitches for smartphone deals.

I switched to social networks, where big companies like AT&T and Verizon
often engage directly with consumers. There was nothing on X (formerly Twitter), not even in the replies space. Just more happy talk about their networks and, on Verizon, a post wondering if Beyonce could break the network (a holdover from her Super Bowl 58 ad).

I posted something on X to gauge the scale of the issue and the number of replies shocked me. How's your network this morning? DownDetector has

It would be hours before any of the major networks stepped forward to acknowledge the issues. Early on, T-Mobile said there was nothing wrong with its network. Verizon eventually gave me a similar comment. I noticed,
however, that both Verizon and AT&T had started responding to customer complaints on X, and it was clear there were at least some issues.

Finally, AT&T sent me an official statement:

Some of our customers are experiencing wireless service interruptions this morning.We are working urgently to restore service to them.We encourage the use of Wi-Fi calling until service is restored.

The "some" part sounded like wishful thinking, considering that some states, like Texas, seemed to have lost almost all AT&T service.

Verizon's comment pointed to something I hadn't considered at first. A representative told me: "Verizon's network is operating normally. Some customers experienced issues this morning when calling or texting with customers served by another carrier. We are continuing to monitor the situation."

What the carrier meant is that when a big network like AT&T goes out, it
makes it harder for other networks to do their job, meaning calls from
Verizon and T-Mobile to customers on the AT&T network were also failing. It's fair to assume that Verizon and T-Mobile customers might log that as their
own network's failure, since there would be no way for them to know about AT&T's problems. So, what DID happen?

Still, the lack of information and explanation has opened the door to sometimes wild conjecture.

Initially, because the outage seemed so widespread and network agnostic, customers started comparing the incident to the recent Julie Roberts apocalyptic film, Leave the World Behind where all the networks going down is part of the plot.

There is, though, no indication that this is a cyber attack.

Some have floated the idea of a solar flare. NASA did report a pair of strong ones in the last 24 hours and such flares have been known to disrupt some communications. Still, the duration of this outage belies that possibility.

Maybe it's a hardware issue. Maybe not.

While I get that AT&T would like to perform a post-mortem before telling us what caused the Big Outage of 2024, I don't think they can wait that long. These providers already waited too long to acknowledge the outage and, in our current conspiracy theory climate, can't afford to leave us in the dark for hours.

Long term, this may be a reminder that our cellular infrastructure is not as strong as we think we need it to be. After many of us woke up to our networks being on the fritz, this is an equally alarming wake-up call for AT&T. You might also like The best phone: top smartphones in the US right now ...
