New York Attorney General Letitia James announced Thursday that her office is investigating the cause of the recent AT&T wireless network outage and the company's response to the incident that left thousands of consumers without service for hours.

"Nationwide outages are not just an inconvenience, they can be dangerous, and it’s critical that we protect consumers when an outage occurs," James said in a statement.

AT&T customers nationwide were left unable to place calls, send text messages or access the internet for up to 12 hours during the Feb. 22 outage, leaving "many unable to contact loved ones, conduct business, or access emergency services," the office said in a statement.

The AT&T network outage resulted in about 73,000 outage reports on Downdetector, a website that tracks internet and cellular network outages.

FOX Business reached out to AT&T for comment.
