AT&T has been struggling to keep up with demand on its data network since the launch of the iPhone 3G. Tests and speculation have all but absolved the iPhone 3G of any inherent defect as the root of sluggish data network performance on AT&T’s 3G network. At this point, AT&T’s recently upgraded 3G network is seemingly to blame for problematic 3G performance.
This morning, AT&T added some icing to their bitter 3G-cake when the No. 1 US wireless carrier’s data network took a nose dive. Reports indicate that AT&T customers on the East Coast saw their local 3G and EDGE networks go completely dark for 10-12 hours. The data network outage affected Massachusetts, New York, Rhode Island, Pennsylvania, Maryland, Virginia, Illinois and Missouri – leaving users without access to emails and unable to surf the web. The voice network was still operational, allowing for text messages and voice calls.
AT&T says that they are looking in to the cause of the data network outage.
