SIOUX FALLS, S.D.-Midco officials say they have yet to identify what was at the heart of a disruption of Internet and email service that occurred Friday, Jan. 13.
The service interruption affected about 300,000 Midco customers throughout South Dakota, North Dakota and Minnesota, including the Fargo-Moorhead area. The issues began about 8:15 a.m. Friday and were largely resolved by 5 p.m.
"We don't know the root cause (of the problem), but we have some preliminary causes," Jon Pederson, Midco's Chief Technology Officer, said in a written statement.
"We have some routing equipment that routes traffic throughout the network and upon close inspection it was found to be at 100 percent utilization. We believe there was a traffic loop that caused that utilization to spike and that cut off some of our network resources," Pederson said in the statement.
Paige Pearson Meyer, Midco's director of public and media relations, said on Monday, Jan. 16, that many of the problems customers experienced were resolved by about 10:15 a.m. Friday, although she added that some customers continued to experience problems throughout the day.
She said in some cases the extended problems were resolved once customers rebooted their modems.
Pearson Meyer said the problems were not believed to be caused by any external issues, such as hacking.
