Computer meltdown takes a toll on U.K. grocer’s home delivery service

A computer glitch is blamed for canceled orders and growing frustrations among Tesco’s home delivery customers on Tuesday.



An IT meltdown impacted orders filtering into the U.K.-based supermarket giant’s online grocery shopping system. The glitch impacted orders being placed online, as well as those scheduled for delivery, according to customer posts on Twitter.



Britain’s biggest supermarket said up to 10% of orders had been affected. The issue impacted customers nationwide, according to The Guardian.



Tesco used Twitter to address shopper concerns. "We cancelled a high volume of orders today due to an IT issue, so this has had a knock on effect. Sorry for the inconvenience,” the grocer said in one tweet.



Tesco continued to field questions and complaints on social media well into Wednesday, responding directly to individual Twitter posts. Customers were also offered a 10 pound ($12.66) voucher as compensation, and were asked to re-arrange their deliveries online, according to the BBC.



While the grocer continued to resolve affected orders on Wednesday, some customers remained caught in the aftermath. “Due to a high volume of cancellations all of our slots [Tuesday] were taken. I'm really sorry for the inconvenience,” according to one of Tesco’s Twitter posts.
