AT&T is DOWN! American customers hit with mobile phone outage that is leaving devices on SOS

AT&T is down for thousands of Americans across the nation - three months after a widespread glitch left people without service for hours.

Wednesday's issues appeared around 4am ET and are plaguing mobile phones and internet.

DownDetector, a website that monitors online outages, shows customers in Chicago, Dallas, Phoenix and other major cities are experiencing problems.

Some customers have said they plan to switch to another carrier today due to AT&T's service being disrupted three times in the past two months. 

This is a developing story... more updates to come 

DownDetector's website shows issue reports for AT&T began to flood in around 10am ET on Tuesday, but has since jumped to more than 1,300 users as of 7am ET.

Approximately 58 percent of users cited issues with their mobile phones, 32 percent do not have a signal and 11 percent are having issues with mobile internet.   

However, the outage is not hitting all American customers at the moment. 

Users flocked to Elon Musk's X early Wednesday morning to share their frustrations about limited cell service, but to ask the masses if they are also experiencing issues. 

One X user stated that they are switching phone carriers today due to AT&T going down three times in the past two months. 

Others shared that they expect to receive a discount on their June bill. 

The current outage has reminded customers of the major glitch that hit in February, which knocked out service for more than 70,000 AT&T users for nearly the entire day.

The spike of that outage also occurred around 4am ET and left users' devices on SOS, which means there is not a connection.
