Target’s website was unable to keep up with on-line traffic, as record Cyber Monday numbers cause the site to crash, preventing shoppers from accessing the site. USA Today reports that the site began having issues around 10 a.m. Customers browsing the site were presented with a message telling them to “hold tight.”

A virtual line was set up to help calm the traffic, giving access to the site little by little. Some customers are still receiving apology messages and are being asked to return to the site later on.

Katie Boylan, a spokesperson for Target says, “We are seeing an absolutely extraordinary response to our Cyber Monday offer.” As part of their Cyber Monday deals, Target was offering customers 15 percent off all items, with free shipping on all orders. Boylan continued, saying, “The traffic, the demand, the orders are absolutely through the roof.”

The volume of sales for Cyber Monday so far is already twice that of Thanksgiving day’s numbers, the retailer’s busiest day. According to the National Retail Federation, more people chose to shop online over the Thanksgiving weekend rather in physical retail stores.

Paypal joined Target among companies that had issues on Cyber Monday. The company “experienced a brief, intermittent interruption” in their service, according to a statement. Neiman Marcus had site issues Friday, which lead the store to extending its Black Friday promotion.

Despite Target’s success, the National Retail Federation expects fewer Cyber Monday shoppers compared to last year’s numbers.
