Nissan N. America Dealer Comms Back Online

The system used by Nissan dealers in North America to report sales, check recalls, file warranty claims and place orders for cars and repair parts is back online after a four-day outage.

The network, known as NNANet, went offline on Saturday because of a power outage at a Nissan data center in Denver. The carmaker says the system was restored to full operational status late Wednesday, Automotive News reports.

It isn’t clear what caused the power outage or why it took four days to fix it.
