AT&T Inc. (T) successfully resolved a significant software glitch that led to a disruption in wireless services for some users on Tuesday evening.

The problem initially surfaced around 5 p.m. ET, escalating to its peak by 7 p.m. ET, as monitored by Downdetector, a platform that tracks service outages. By 10 p.m. ET, the number of reported issues had noticeably decreased, indicating that the situation was under control.

This service interruption affected several major metropolitan areas including Dallas, Charlotte, Los Angeles, Houston, Chicago, and New York City. Despite the widespread impact, the disruption was not nationwide, limiting its overall reach.

The outage raised concerns particularly because it interfered with the ability of some customers to make emergency 911 calls. Various government entities across the nation reported these potential impacts, with cities like Pinole, California, and North Little Rock, Arkansas, specifically confirming the issue. Fortunately, these cities later reported that normal service had been restored.

An AT&T spokesperson addressed the situation to CNN on Wednesday, stating, “We’ve resolved a software issue that disrupted the ability of a limited number of our customers to connect to our wireless network. We apologize for the inconvenience and we appreciate our customers’ patience as we work to resolve this issue.”

This incident comes at a crucial time for AT&T, following its recent financial performance and market activities. In late July, the company announced its second-quarter results which highlighted a balance between growth and profitability. During this period, AT&T added an impressive 997,000 wireless customers, although it fell slightly short of revenue expectations.

AT&T continues to be a favored choice among dividend investors due to its attractive high yield. In early August, financial analysts recommended purchasing AT&T shares, citing the appealing dividend yield as a key reason.

In terms of stock performance, AT&T’s shares closed at $19.65 on Tuesday, reflecting a 0.56% decrease for the day. Pre-market trading showed a slight dip of 0.25%. However, year-to-date, AT&T’s stock has gained 13.91%, according to data from Benzinga Pro.

In related news, Amazon’s CEO Andy Jassy announced that the company’s AI assistant has saved $260 million and 4.5K developer-years of work, underscoring its transformative impact.
