The outage on Sunday lasted about 90 minutes and apparently did not affect all of Target’s roughly 1,800 stores. An unrelated problem on Saturday had been much more widespread and had lasted about two hours.
After reports surfaced that Target was blaming NCR, NCR's stock took a hit in early trading, dropping 4%. But the stock rebounded later in the day and was in positive territory by mid-afternoon.
Mobile Payments Today reported that Target officials had told them that NCR technology is used to process payments from its stores.
NCR has three data centers, according to Data Center Dynamics, a web-based news source covering data: Ashburn, Virginia, Westlake, California and Dayton, Ohio.
Dayton was the original home for NCR, which was founded in 1884 as National Cash Register. The company moved to Gwinnett County in 2009, enticed by more than $100 million in state and local incentives.
Less than six years later, the company announced plans to move its headquarters to Atlanta's Midtown.
