As online video increasingly shifts to mobile devices, the wireless network outage across much of the Southeast on Tuesday called into question the reliability of major carriers' networks. A hardware issue on AT&T's wireline network was pinpointed as the cause. At least 24,000 customers in parts of Indiana, Kentucky, Alabama and Tennessee were affected, according to reports from DownDetector.com.
While service was restored to most customers by Tuesday night, AT&T said it will continue to investigate the root cause of the incident. AT&T's wireline network serves several other major wireless carriers in the region, including T-Mobile, Sprint and Verizon Wireless.
