While the issue has been resolved, the reason behind the outage has not been disclosed. This gives space to speculation as to the reason behind the said outage, which evidently impacted users nationwide. This could be a technical issue, there has been a recent increase in cyberattacks in the telecommunications sector, with many companies being prime targets of the hacker community.

Earlier this year, there was another disruption that stirred concerns. Back in February, the FCC and New York Attorney General Letitia James began investigating an AT&T outage that impacted over 70,000 customers and persisted for over 10 hours. There were initial worries that this might have been the result of a cyberattack. However, AT&T clarified that the issue was due to a software update, thereby dismissing the cyberattack concerns.

However, in March, AT&T experienced a data breach, with personal information belonging to 73 million current or former customers leaked online. The U.S. telecom giant stated that the data, including addresses, social security numbers, and passcodes, was found on the dark web.

Although AT&T had not found evidence that the data was stolen, it engaged cybersecurity experts to conduct an investigation. In response to the incident, the company has reset customer passcodes and urged individuals to remain alert by monitoring their account activities and credit reports.

The compromised data, dating back to 2019 or earlier, impacted 7.6 million current customers and 65.4 million former account holders. It encompassed details like full names, email addresses, and dates of birth. However, AT&T confirmed that no financial information was disclosed in the said leak.
