Neiman Marcus is living every retailer's worst nightmare.
On the busiest shopping day of the year, Black Friday, the luxury retailer's e-commerce site has suffered an outage that CNBC reports has been going on since about 8 a.m. Eastern time. As of shortly after noon, the site was still not accessible.
A spokesperson for Neiman told Fortune the company is "working fervently to get it back up."
Like other luxury retailers, Neiman doesn't do the full-on Thanksgiving/Black Friday overnight insanity, preferring to open stores on Friday morning. But it's still a big shopping day, even for people not looking for a TV. Neiman's site had been offering deals up to 60% on Black Friday.
And in the case of Neiman, an e-commerce outage is particularly bad news: the department store chain gets about 25% of revenue online, making it one of the most e-commerce reliant brick-and-mortar stores.
The outage comes two years after a data breach hit Neiman in time for the holiday season in which hackers stole credit card information from as many as 350,000 customers.
